Systems displaying competing interactions of some kind are widespread - much more, in fact, as commonly anticipated (magnetic and Ising-type interactions or the dynamics of DNA molecules being only two popular examples). Written for researchers in the field with different professional backgrounds, this volume classifies phenomena not by system but rather by the type of competing interactions involved. This allows for a straightforward presentation of the underlying principles and the universal laws governing the behaviour of different systems. Starting with a historical overview, the author proceeds by describing self-competitions of various types of interactions (such as diploar or multipol...
In this work, magnetic atoms on surfaces are studied with low-temperature scanning tunneling microscopy. Motivated by the idea to use single atoms as magnetic bits, the factors that allow or prevent long-term stability of their magnetic moments are investigated. Lifetimes of up to several minutes can be achieved for the magnetic moments of holmium atoms on a Pt(111) surface, resulting from the combined symmetries of the system. Corresponding theoretical calculations are presented and evaluated.
This book provides a comprehensive overview of the fascinating recent developments in atomic- and nanoscale magnetism, including the physics of individual magnetic adatoms and single spins, the synthesis of molecular magnets for spintronic applications, and the magnetic properties of small clusters as well as non-collinear spin textures, such as spin spirals and magnetic skyrmions in ultrathin films and nanostructures. Starting from the level of atomic-scale magnetic interactions, the book addresses the emergence of many-body states in quantum magnetism and complex spin states resulting from the competition of such interactions, both experimentally and theoretically. It also introduces novel microscopic and spectroscopic techniques to reveal the exciting physics of magnetic adatom arrays and nanostructures at ultimate spatial and temporal resolution and demonstrates their applications using various insightful examples. The book is intended for researchers and graduate students interested in recent developments of one of the most fascinating fields of condensed matter physics.
Using the cosmos as a backdrop, Rodney Cotterill delivers a fascinating journey of Nature's materials, from the atom to the living organism. This is a beautifully illustrated, expanded account of the highly praised Cambridge Guide to the Material World. The author seamlessly blends the physics, chemistry and biology of Nature, portraying matter with all its elegance and flaws. Although the book is divided into material types, the author connects concepts and pinpoints commonalities between the inorganic and organic domains. It challenges the reader to question our structured view of the world and whether this limits our scientific endeavour, aptly demonstrated by the new chapter devoted exclusively to the mind. Through the breadth of topics and engaging prose, this book will act as a superb introduction to material science for students and those intrigued by the material world we live in.
Spintronics Handbook, Second Edition offers an update on the single most comprehensive survey of the two intertwined fields of spintronics and magnetism, covering the diverse array of materials and structures, including silicon, organic semiconductors, carbon nanotubes, graphene, and engineered nanostructures. It focuses on seminal pioneering work, together with the latest in cutting-edge advances, notably extended discussion of two-dimensional materials beyond graphene, topological insulators, skyrmions, and molecular spintronics. The main sections cover physical phenomena, spin-dependent tunneling, control of spin and magnetism in semiconductors, and spin-based applications. Features: Pres...
In Mondo Nano Colin Milburn takes his readers on a playful expedition through the emerging landscape of nanotechnology, offering a light-hearted yet critical account of our high-tech world of fun and games. This expedition ventures into discussions of the first nanocars, the popular video games Second Life, Crysis, and BioShock, international nanosoccer tournaments, and utopian nano cities. Along the way, Milburn shows how the methods, dispositions, and goals of nanotechnology research converge with video game culture. With an emphasis on play, scientists and gamers alike are building a new world atom by atom, transforming scientific speculations and video game fantasies into reality. Milburn suggests that the closing of the gap between bits and atoms entices scientists, geeks, and gamers to dream of a completely programmable future. Welcome to the wild world of Mondo Nano.
This is the first book providing overview of magnetism in curved geometries, highlighting numerous peculiarities emerging from geometrically curved magnetic objects such as curved wires, shells, as well as complex three-dimensional structures. Extending planar two-dimensional structures into the three-dimensional space has become a general trend in multiple disciplines across electronics, photonics, plasmonics and magnetics. This approach provides the means to modify conventional and even launch novel functionalities by tailoring the local curvature of an object. The book covers the theory of curvilinear micromagnetism as well as experimental studies of geometrically curved magnets including...
