Book Description
This book is devoted to the rapidly developing field of oxide thin-films and heterostructures. Oxide materials combined with atomic-scale precision in a heterostructure exhibit an abundance of macroscopic physical properties involving the strong coupling between the electronic, spin, and structural degrees of freedom, and the interplay between magnetism, ferroelectricity, and conductivity. Recent advances in thin-film deposition and characterization techniques made possible the experimental realization of such oxide heterostructures, promising novel functionalities and device concepts. The book consists of chapters on some of the key innovations in the field over recent years, including strongly correlated oxide heterostructures, magnetoelectric coupling and multiferroic materials, thermoelectric phenomena, and two-dimensional electron gases at oxide interfaces. The book covers the core principles, describes experimental approaches to fabricate and characterize oxide heterostructures, demonstrates new functional properties of these materials, and provides an overview of novel applications.

Book Description
The physics of transition metal oxides has become a central topic of interest to condensed-matter scientists ever since high temperature superconductivity was discovered in hole-doped cuprates with perovskite-like structures. Although the renewed interest in hole-doped perovskite manganites following the discovery of their colossal magnetoresistance (CMR) properties, began in 1993 about a decade after the discovery of high temperature superconductivity, their first investigation started as early as 1950 and basic theoretical ideas were developed during 1951-1960. Experience in sample preparation and characterization, and in growth of single crystals and epitaxial thin films, gained during the research on high temperature superconductors, and the development of theoretical tools, were very efficiently used in research on CMR manganites. In early nineties it appeared to many condensed matter physicists that although the problem of high temperature superconductivity is a difficult one to solve, a quantitative understanding of CMR phenomena might be well within reach. This book is intended to be an account of the latest developments in the phys ics of CMR manganites. When I planned this book back in 2000, I thought that research on the physics of CMR manganites would be more or less consolidated by the time this would be published. I was obviously very optimistic indeed. We are now in 2003 and we still do not have a quantitative understanding of the central CMR effect. Meanwhile the field has expanded. It is still a very active field of research on both the experimental and theoretical fronts.

Book Description
Infinite in All Directions is a popularized science at its best. In Dyson's view, science and religion are two windows through which we can look out at the world around us. The book is a revised version of a series of the Gifford Lectures under the title "In Praise of Diversity" given at Aberdeen, Scotland. They allowed Dyson the license to express everything in the universe, which he divided into two parts in polished prose: focusing on the diversity of the natural world as the first, and the diversity of human reactions as the second half. Chapter 1 is a brief explanation of Dyson's attitudes toward religion and science. Chapter 2 is a one–hour tour of the universe that emphasizes the diversity of viewpoints from which the universe can be encountered as well as the diversity of objects which it contains. Chapter 3 is concerned with the history of science and describes two contrasting styles in science: one welcoming diversity and the other deploring it. He uses the cities of Manchester and Athens as symbols of these two ways of approaching science. Chapter 4, concerned with the origin of life, describes the ideas of six illustrious scientists who have struggled to understand the nature of life from various points of view. Chapter 5 continues the discussion of the nature and evolution of life. The question of why life characteristically tends toward extremes of diversity remains central in all attempts to understand life's place in the universe. Chapter 6 is an exercise in eschatology, trying to define possible futures for life and for the universe, from here to infinity. In this chapter, Dyson crosses the border between science and science fiction and he frames his speculations in a slightly theological context.

Book Description
The scattering of spin one-half fermions (electrons and neutrons) in multilayer systems containing magnetic nano-elements is a broad avenue for revealing transport properties of materials such as conductance, coherent (ballistic) resistance, and the spin polarization of the electric current. The spin dependent scattering is also a diagnostic tool for the study of magnetic structures of magnetic elements themselves (neutrons). From a theoretical point of view, the solution of one-dimensional scattering problem is reduced to the transfer matrix problem of the spin-polarized (unpolarised) waves on a system consisting of finite potential barriers, characterized by classical magnetization vectors. Their combination together with the vector of the spin polarization of the incident wave (if it is polarized) forms a system of allocated general collinear, and in some cases noncoplanar to the interface directions. As a result, the system becomes more complex and rich with additional degrees of freedom (so-called degrees of noncollinearity). The transport and magnetic characteristics are substantially dependent on these degrees of freedom, and in many cases allow the governing of them. For example, consider a system consisting of two barriers with noncollinear magnetizations. It is shown that it possesses the basic spintronic properties; these include a giant (tunneling) magnetoresistance and valve effect. Besides this, an effect similar to that known in optics as the Malus effect is possible. In the multi-barrier system, one can add also other degrees of freedom, such as the ratio of the lengths of various magnetic domains, which is extremely important for the control of quantum interference effects. The described systems are interesting from the viewpoint of the possibility to design nano devices with predetermined properties, as well as the possibility of tuning those properties due to the additional degrees of freedom. To study these systems, generalization of the well-known transfer-matrix method for non-collinear systems is carried out. These exact calculations illustrate important clues and exciting opportunities that could be utilized when synthesizing a barrier profile heterostructure containing magnetic layers. Recent developments in the field of spin polarized transport should lead to many scientific advances in surface science, magnetism, solid state physics and tunneling.

Book Description
The discovery of high temperature superconductivity has not only opened many possibilities for potential technical applications, but has also provided a unique, challenging research subject for condensed matter physics and material sciences. High temperature superconductivity appears in systems with strong electron correlation and constitutes one of the key issues in condensed matter physics. The understanding of its mechanism will therefore greatly promote the future developments of this branch of science. During the last ten years great progress has been made in both fundamental and application-oriented research. Expanding knowledge of the physical properties in the superconducting as well as the normal state in preparing the way to an understanding of the underlying mechanisms. The accumulated experience in materials processing enables technical applications. All these aspects of high-Tc superconductivity and recent work on "traditional" superconductors have been exposed at the Beijing conference. The present volume is a separate edition of part I of the extensive Proceedings of the Fifth International Conference on Materials and Mechanisms of Superconductivity - High Temperature Superconductors. It contains the plenary, tutorial and invited papers, and gives a comprehensive account of the state-of-the-art as of March 1997.
