This book was released on 2012-12-02 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Acoustics, Volume XX: Ultrasonics of High-Tc and Other Unconventional Superconductors covers the many acoustic studies of the high-Tc superconductors. This book is composed of 10 chapters that include some unconventional superconducting systems, such as superfluid 3He, heavy Fermion superconductors, and magnetic re-entrant superconductors. The introductory chapter summarizes the results that have been observed in Bardeen, Cooper, and Schriefer superconductors as functions both of temperature and magnetic field. The subsequent chapters deal with the theoretical and experimental aspects of ultrasonic study of some unconventional superconductors. Considerable chapters are devoted to the measurements with sound waves on the sintered high-Tc superconducting systems. These chapters examine first the temperature and magnetic field dependence of the velocity and elastic constants in sintered high-Tc superconductors, as well as the sound absorption and dispersion measurements on single crystals of these superconductors. Discussions on the small-sample resonant ultrasound technique that uses thin piezoelectric films and the effect of oxygen on superconducting properties and the response of sound to these additions are also provided in these chapters. The concluding chapter presents a theoretical foundation for sound measurements in the superconducting state, emphasizing the effects of multigap structures and gas anisotropy on sound attenuation in the superconducting state of the cuprate superconductors. This volume will be of great benefit to researchers in the fields of electronics technology and in applied and engineering mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic techniques have been used to characterize the properties of high Tc superconductors. A model is being developed to explain the radiation losses from a resonating fused silica sample. A new very sensitive resonant technique was developed for studying vortex motion in the superconducting state of an untwinned single crystal of YBCO. Evidence is obtained for a transition from a soft vortex system to a rigid strongly interacting vortex system in the vicinity of the superconducting transition temperature. A percolation model developed in our group to describe surface acoustic wave attenuation in a granular superconducting film was modified to include the resistivity of the individual grains in a matrix of Josephson junctions. SAW measurements using a pontoon technique on both a single crystal and a thin film of YBCO demonstrate the importance of pinning sites in determining the nature of a vortex transition; the vortex system will undergo a depinning transition if the pinning density is large and a melting transition if it is small. Resonant ultrasonic spectroscopy data obtained as a function of gas pressure has been analyzed.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic techniques have been used to characterize properties of high T sub c and other unconventional superconductors. Attenuation and velocity measurements with shear waves have been performed on a sintered sample of HgBa2CuO4 and single crystal and melt textured samples of YBCO as a function of magnetic field. Anomalous behavior is observed which may be due to the fact that sound waves are sensitive to the total number of flux lines sampled, regardless of their orientation. A pontoon technique was used to launch surface acoustic waves SAW through a single crystal platelet of YBCO. A relative maximum in attenuation is observed at around 90K which may be associated with a relaxation process. Measurements on a SAW reflective array compressor made of superconducting YBCO appear to indicate that the YBCO reflecting chevrons are more effective in reflecting the SAW in the normal state than in the superconducting state. The insertion loss of a SAW delay line made with YBCO interdigital electrodes decreased when the electrodes became superconducting. A theoretical model has been developed to quantitatively explain these results.

This book was released on 2006-04-11 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The Frontiers of Knowhledge (to coin a phrase) are always on the move. - day’s discovery will tomorrow be part of the mental furniture of every research worker. By the end of next week it will be in every course of graduate lectures. Within the month there will be a clamour to have it in the undergraduate c- riculum. Next year, I do believe, it will seem so commonplace that it may be assumed to be known by every schoolboy. “The process of advancing the line of settlements, and cultivating and c- ilizing the new territory, takes place in stages. The original papers are p- lished, to the delight of their authors, and to the critical eyes of their readers. Review articles then provide crude sketch plans, elementary guides through the forests of the literature. Then come the monographs, exact surveys, mapping out the ground that has been won, adjusting claims for priority, putting each fact or theory into its place” (J. M. Ziman, Principles of the Theory of Solids (Cambridge University Press, 1972) p.v). The main purpose of the book is to present the mechanism of - perconductivity discovered in 1986 by J. G. Bednorz and K. A. Müller, and to discuss the physics of superconductors. The last chapter of the book presents analysis of tunneling measurements in cuprates. The book is - dressed to researchers and graduate students in all branches of exact sciences.

This book was released on 2009-11-20 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first monograph that strives to give a complete and detailed description of the collective modes (CMs) in unconventional superfluids and superconductors (UCSF&SC). Using the most powerful method of modern theoretical physics OCo the path (functional) integral technique OCo authors build the three- and two-dimensional models for s -, p - and d -wave pairing in neutral as well as in charged FermiOCosystems, models of superfluid BoseOCosystems and FermiOCoBoseOComixtures. Within these models they study the collective properties of such systems as superfluid 3 He, superfluid 4 He, superfluid 3 He- 4 He mixtures, superfluid 3 He-films, superfluid 3 He and superfluid 3 He- 4 He mixtures in aerogel, high temperature superconductors, heavy-fermion superconductors, superconducting films etc. Authors compare their results with experimental data and predict a lot of new experiments on CMs study. This opens for experimentalists new possibilities for search of new intriguing features of collective behavior of UCSF&SC. The monograph creates the new scientific direction OCo the spectroscopy of collective modes in unconventional superfluids and superconductors. It will be useful for both theorists and experimentalists, studying superfluids and superconductors, low temperature physics, condensed matter physics, solid state physics. It could be used by graduate students specializing in the same areas. Sample Chapter(s). Introduction (162 KB). Chapter 1: Functional Integration Method (369 KB).

This book was released on 2000-10-23 with total page 2513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound waves propagate through galactic space, through two-dimensional solids, through biological systems, through normal and dense stars, and through everything that surrounds us; the earth, the sea, and the air. We use sound to locate objects, to identify objects, to understand processes going on in nature, to communicate, and to entertain. The elastic properties of materials determine the velocity of sound in them and tell us about their response to stresses something which is very important when we are trying to construct, manufacture, or create something with any material. The Handbook of Elastic Properties of Materials will provide these characteristics for almost everything whose elastic properties has ever been measured or deduced in a concise and approachable manner. Leading experts will explain the significance of the elastic properties as they relate to intrinsic microscopic behavior, to manufacturing, to construction, or to diagnosis. They will discuss the propagation of sound in newly discovered or created materials, and in common materials which are being investigated with a fresh outlook. The Handbook will provide the reader with the elastic properties of the common and mundane, the novel and unique, the immense and the microscopic, and the exhorbitantly dense and the ephemeral.. You will also find the measurement. And theoretical techniques that have been developed and invented in order to extract these properties from a reluctant nature and recalcitrant systems. Key Features * Solids, liquids and gases covered in one handbook * Articles by experts describing insights developed over long and Illustrious careers * Properties of esoteric substances, such as normal and dense stars, superfluid helium three, fullerness, two dimensional solids, extraterrestial substances, gems and planetary atmospheres * Properties of common materials such as food, wood used for musical instruments, paper, cement, and cork * Modern dynamic elastic properties measurement techniques

Available in PDF, EPUB and Kindle. Book excerpt: Unconventional superconductivity (or superconductivity with a nontrivial Cooper pairing) is believed to exist in many heavy-fermion materials as well as in high temperature superconductors, and is a subject of great theoretical and experimental interest. The remarkable progress achieved in this field has not been reflected in published monographs and textbooks, and there is a gap between current research and the standard education of solid state physicists in the theory of superconductivity. This book is intended to meet this information need and includes the authors' original results.
