Available in PDF, EPUB and Kindle. Book excerpt: Although there has been steady progress in understanding aspects of epitaxial growth throughout the last 30 years of modern surface science, work in this area has intensified greatly in the last 5 years. A number of factors have contributed to this expansion. One has been the general trend in surface science to tackle problems of increasing complexity as confidence is gained in the methodology, so for example, the role of oxide/metal interfaces in determining the properties of many practical supported catalysts is now being explored in greater detail. A second factor is the recognition of the potential importance of artificial multilayer materials not only in semiconductor devices but also in metal/metal systems because of their novel magnetic properties. Perhaps even more important than either of these application areas, however, is the newly-discovered power of scanning probe microscopies, and most notably scanning tunneling microscopy (STM), to provide the means to study epitaxial growth phenomena on an atomic scale under a wide range of conditions. These techniques have also contributed to revitalised interest in methods of fabricating and exploiting artificial structures (lateral as well as in layers) on a nanometre scale.This volume, on Growth and Properties of Ultrathin Epitaxial Layers, includes a collection of articles which reflects the present state of activity in this field. The emphasis is on metals and oxides rather than semiconductors.

This book was released on 2009-07-20 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work in this thesis focuses on the preparation of epitaxial Nd-Fe-B thin films using pulsed laser deposition for good hard magnetic properties. They are suitable for a basic understanding of the intrinsic magnetic properties. Compositional control was necessary to achieve phase formation with improved magnetic properties. Nd-Fe-B samples were prepared on single crystal MgO (001) substrates with different buffer layers in order to obtain good textures with different surface morphology. The smooth and continuous epitaxial films were suitable for performing magnetization measurements under stress. Although the magnetostriction is easily neglected in the Nd2Fe14B compound, distinguishable inverse magnetostriction was observed by conventional tensile elongation with a flexible substrate. As a result, anisotropic strain in the film, which breaks the in-plane symmetry, affected the opening angle during the spin reorientation. Therefore an elliptical distortion of the in-plane anisotropy below the spin reorientation temperature of Nd2Fe14B was obtained, whereas the transition temperature itself was not influenced significantly.

Download or read book Synthesis and Characterization of Ferromagnetic Nanoparticles written by Kazuaki Yano and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferromagnetic nanoparticles and their bimagnetic nanoparticles with uniform size distribution have drawn great attention in the past decades because of their unique magnetic properties and potential applications in high density recording media, exchange-spring permanent magnets and biotechnology. In this thesis, synthesis and characterization of ferromagnetic nanoparticles (FePt, Sm-Co system) and bimagnetic nanoparticles (FePt/Fe3O4, FePt/Au) are reported. FePt nanoparticles with different sizes and compositions were successfully synthesized via chemical synthesis. FePt particle size was tuned to a range of from 3 nm to 8 nm with 1 nm accuracy by changing the surfactant to Pt precursor ratio. By optimizing the amount of Fe3O4 phase in exchange-coupled FePt/Fe3O4 nanoparticles, the highest (BH) max of 17.6 MGOe was achieved in 6 nm FePt/Fe3O 4 particles after proper annealing, which is 35% higher than 13 MGOe for single-phase isotropic FePt nanoparticles. As-synthesized FePt particles with average size of 8 nm were annealed using Rapid Thermal Annealing (RTA) treatment with various temperatures and time. It was found that FePt nanoparticles can be transferred from disordered A1 phase to ordered L10 phase in several seconds at above 600°C, which is much shorter than the time needed for furnace annealing. The transmission electronic microscopy (TEM) and X-ray diffraction studies revealed that the average particle size of RTA treated FePt nanoparticles is smaller than that of the furnace annealed particles and no excessive particle sintering and agglomeration were observed in the RTA treated particles. FePt/Au core/shell nanoparticles have been successfully synthesized using seed mediated chemistry. The high resolution TEM (HRTEM) with Selected Area Electron Diffraction (SAED) and Nano-Beam Diffraction (NBD) analyses confirmed the core/shell structure of FePt/Au nanoparticles. The VU-Vis measurement revealed that FePt/Au core/shell nanoparticles show a red shift of surface plasmon absorption band compared to pure Au nanoparticles. The FePt/Au core/shell nanoparticles showed ferromagnetism after annealing at optimum temperature. Moreover, the water soluble FePt/Au core/shell nanoparticles were achieved by ligands exchange. Sm-Co particles were prepared via surfactants-assisted ball milling and separated into slurries and nanoparticles by size selection process. As-milled particles were then annealed by different types of annealing techniques to improve the magnetic properties. XRD studies revealed that after forming gas and hydrothermal annealing the Sm-Co particles were oxidized and decomposed into Sm2O3 and magnetically soft phase (FeCo, Co), resulting in the decrease of coercivity. Coercivity of Sm2Co 17 slurries increased by vacuum annealing when the ball milling time is less than 5 h. Highest Hc of 7.5 kOe was achieved in 1 h ball-milled particles, which is 35% higher than the coercivity of non-annealed particles. For the nanoparticles, it was difficult to increase or even maintain the magnetic properties after annealing because of high oxidation affinity of nanoparticles.
