Book Description
Mixed metal oxides with iron oxide as a main constituent are called as ferrites. Ferrites are ferrimagnetic cubic spinels which possess combine properties of magnetic materials and electrical insulators; they have been intensively investigated in being the subject of great interest because of their importance in many applications. Spinel ferrites have received special attention over the last decade because of their extensive use in many applications such as transmitting microwave devices, computer memory chips, magnetic recording media, and radio frequency coil fabrication, transformer cores, catalysis, photocatalysis, magnetically guided drug delivery, hyperthermia and many branches of telecommunication and electronic engineering. The features of spinel structure show that these ferrites have eight formula units per unit cell. A unit cell comprises eight tetrahedral and sixteen octahedral sites with AB2O4 where (A) and (B) refer to the tetrahedral and octahedral cation sites respectively. In inverse spinel structure, the tetrahedral (A) site.

Book Description
Spintronics manipulates individual magnetic moments to integrate logic functions and non-volatile information storage on the same platform. As is often the case in condensed matter science, advances are made through the synthesis of novel materials and high quality new physics materials. Giant magnetoresistance and dilute magnetic semiconductors are two such examples. However, the remarkable potential of spintronics for quantum computation faces major challenges when it comes to controlling simultaneously several qbits encoded in magnetic moments.After a brief introduction to concepts in nanomagnetism and spintronics, the text reviews recent techniques and their achievements in the synthesis and fabrication of magnetic nanostructures. The methods presented here emphasize bottom up or top down approaches for nanodots, nanowires and thin films. They include: focused ion beam irradiation, electron beam-induced chemical vapour deposition, chemical, and electrochemical methods. The later part of the book reviews magnetoelectric materials, the giant magnetoresistance in magnetic superlattices, dynamics effects in spin transfer torque oscillators, dilute magnetic oxides, rare earth nitrides with nuclear resonance scattering, and Mössbauer spectroscopy in spintronics. Finally, the last part of this book discusses applications to magnetic storage and bio-magnetism.Nanomagnetism and Spintronics will be useful to graduate students and researchers and engineers in the field of nanoscience.

Book Description
In recent years, the physics community has experienced a revival of interest in spin effects in solid state systems. On one hand, the solid state systems, particularly, semiconductors and semiconductor nanosystems, allow us to perform benchtop studies of quantum and relativistic phenomena. On the other hand, this interest is supported by the prospects of realizing spin-based electronics, where the electron or nuclear spins may play a role of quantum or classical information carriers. This book looks in detail at the physics of interacting systems of electron and nuclear spins in semiconductors, with particular emphasis on low-dimensional structures. These two spin systems naturally appear in practically all widespread semiconductor compounds. The hyperfine interaction of the charge carriers and nuclear spins is particularly prominent in nanosystems due to the localization of the charge carriers, and gives rise to spin exchange between these two systems and a whole range of beautiful and complex physics of manybody and nonlinear systems. As a result, understanding of the intertwined spin systems of electrons and nuclei is crucial for in-depth studying and controlling the spin phenomena in semiconductors. The book addresses a number of the most prominent effects taking place in semiconductor nanosystems including hyperfine interaction, nuclear magnetic resonance, dynamical nuclear polarization, spin-Faraday and spin-Kerr effects, processes of electron spin decoherence and relaxation, effects of electron spin precession mode-locking and frequency focussing, as well as fluctuations of electron and nuclear spins.

Book Description
The influence of size effects on the properties of nanostructures is subject of this book. Size and interfacial effects in oxides, semiconductors, magnetic and superconducting nanostructures, from very simple to very complex, are considered. The most general meaning is assumed for size effects, including not only the influence of a reduced dimension/dimensionality, but also specific interfacial effects. Preparation and characterization tools are explained for various nanostructures. The specific applications are discussed with respect to size-related properties. A logic implication of type phenomenon-property-material-application is envisaged throughout this work.
