Available in PDF, EPUB and Kindle. Book excerpt: A System Of Fine Particles Of Magnetic Materials Behaves Differently Than Its Bulk Counterpart. This Book Provides A Comprehensive Background To Understand This Deviation Of Behaviour. After Giving An Introductory Account Of Magnetism, The Book Presents A Discussion On Ferro, Antiferro, Ferri And Weak Ferromagnetism Which Belong To A Class Of Cooperative Phenomena. An Elementary Idea Of Domain Structure Which Explains The Behaviour Of Ferromagnets Has Been Included. The Fine Particles Of Magnetic Materials Have Been Classified According To Grain Size Into Single And Multidomain Particles. In An Assembly Of Fine Single Domain Particles Below A Critical Size, Any Cooperative Alignment Of Dipole Moments May Not Be Possible Because Of Thermal Agitation. As A Result, The Assembly Exhibits Magnetic Behaviour Of A Giant Paramagnetic System Above A Critical Temperature Known As Blocking Temperature. This Phenomenon Known As Superparamagnetism Has Been Presented In Detail. Magnetic Materials Comprising Of Fine Grains Can Also Carry A Faithful Record Of The Geomagnetic Field At The Time Of Cooling Of An Igneous Rock Or Deposition Of A Sedimentary Rock. This Memory Of The Past Geomagnetic Field Is Maintained Through Their Remanent Magnetization, Which Is Extremely Stable. A Detailed Experimental Study Of A Magnetic System Exhibiting Thermoremanent Magnetization (Trm) Due To Its Cooling Below The Critical Temperature In The Presence Of The Residual Magnetic Field Of The Experimental Set Up In The Laboratory Has Been Described. Different Possible Mechanisms On The Origin Of Trm In The Samples Including The Formation Of Fine Lamellae Have Been Discussed. The Last Chapter Presents An Experimental Study On Magnetic Systems Comprising Of Very Fine Magnetic Particles And Exhibiting Superparamagnetism.

Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the contributions to a course, entitled Applied Magnetism, which was the 25th Course of the International School of Materials Science and Technology. The Course was held as a NATO Advanced Study Institute at the Ettore Majorana Centre in Erice, Sicily, Italy between the 1st and 12th July 1992, and attracted almost 70 participants from 15 different countries. The book deals with the theory, experiments and applications of the main topical areas of applied magnetism. These selected areas include the physics of magnetic recording, magnetic and magneto-optic recording devices, systems and media, magnetic fine particles, magnetic separation, domains and domain walls in soft magnetic materials, permanent magnets, magnetoresistance, thin film magneto-optics, and finally, microwave, optical and computational magnetics. The material is organised into I 0 self-contained chapters which together provide a comprehensive coverage of the subject of applied magnetism. The aim is to emphasise the connection between the fundamental theoretical concepts, key experiments and the important technological developments which have been achieved in this field up to the present time. Moreover, when and where possible, pointers to future trends are indicated which hopefully, together with the background material, will promote further advancement of research. The organizing committee would like to acknowledge the sponsorship of the NATO Scientific Affairs Division, the National Science Foundation of the USA, the Science and Engineering Research Council of the UK, the Italian Ministry of Education, the Italian Ministry of University and Scientific Research and the Sicilian Regional Government.

This book was released on 2013-11-11 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of uniform latex particles by polymer chemists of the Dow Chemical Company nearly 50 years ago opened up new exciting fields for scientists and physicians and established many new biomedical applications. Many in vitro diagnostic tests such as the latex agglutination tests, analytical cell and phagocytosis tests have since become rou tine. They were all developed on the basis of small particles bound to biological active molecules and fluorescent and radioactive markers. Further developments are ongoing, with the focus now shifted to applications of polymer particles in the controlled and di rected transport of drugs in living systems. Four important factors make microspheres interesting for in vivo applications: First, biocompatible polymer particles can be used to transport known amounts of drug and re lease them in a controlled fashion. Second, particles can be made of materials which bio degrade in living organisms without doing any harm. Third, particles with modified surfaces are able to avoid rapid capture by the reticuloendothelial system and therefore en hance their blood circulation time. Fourth, combining particles with specific molecules may allow organ-directed targeting.

Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the main ideas and the latest results in the study of electromagnetic materials, as presented at the Symposium on Electromagnetic Materials, ICMAT 2005. The high quality contributions reflect the principle aims of the conference: to provide an international forum for scientists and engineers to report their most recent research findings, to exchange ideas and information, and to nuture and establish research ties. Electromagnetic materials have both civilian and defence applications, such as novel antenna designs, protection against high power transients in densely packed printed circuits, and special frequency response or polarization response to meet component or system specifications. An in-depth understanding of the responses of materials to electromagnetic waves may even enable us to design and fabricate materials with properties not found in nature.

Download or read book Relaxation in Complex Systems and Related Topics written by I.A. Campbell and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the workshop was to bring together specialists in various fields where non-exponential relaxation is observed in order to compare models and experimental results and to examine the general physical principles governing this type of behaviour. Non-exponential relaxation is found in extremely diverse physical systems all of which can be classified as complex. The form of the relaxation is generally parametrized using logarithmic, algebraic or stretched exponential decay forms. The conceptually simplest mechanism for the non-exponential decay is a spectrum of relaxation rates due to non-interacting units each of which relaxes with a different intrinsic time constant. Clear experimental examples can be given where for instance the relaxation of a collection of isolated polymer molecules leads to an overall stretched exponential decay. Non-exponential relaxation is observed in all strongly interacting complex systems (structural glasses, spin glasses, etc ... ) where each elementary unit is in interaction with many other units.
