Opis

A team of outstanding scientists in the field of modern magnetic nanotechnologies illustrates the state of the art in several areas of advanced magneto-electronic devices, magnetic micro-electromechanical systems and high density information storage technologies. The physics and chemistry of nano-scale systems have made rapid advances and there are real prospects of translating exciting scientific findings into a new generation of processes and high technology products with a potential impact on several industrial sectors. In particular the development of nano-structured magnetic materials plays a leading role in the increasing miniaturization of devices with superior performances. The application areas considered are: i) "magneto-electronics," where the control of electron spins in magnetic hetero-structures offers new and improved functionalities in devices of integrated digital electronics. Magnetic random access memories, MRAM are among the principal applications for new non-volatile RAM with fast dynamics, toward the pico-, femto-second range. ii) "magnetic MEMS" (micro-electro-mechanical systems), which are the integration of mechanical and electro/ferromagnetic elements (micro-actuators and sensors) with conventional electronics MEMS, promise a revolution in several product categories. In fact the proposed integration enables the development of smart products, where sensors can gather information from the environment by measuring thermal, magnetic, electric, mechanical, biological chemical, optical characteristics and the electronic section processes the information and the actuator promotes the action realizing a complete control of the environment. iii) "Magnetic recording" is a leading technology in the information storage domain and the most relevant application in the field of magnetics, showing surprising continuous progress over several decades towards the limit of terabit per square inch of areal density.>

Recenzje

From the reviews:

"This book contains the proceedings of a NATO Advanced Study Institute on 'Magnetic Nanostructures for Micro-Electromechanical Systems and Spintronic Applications' held in 2006. The goal of the editors is to provide the reader with a 'state of the art' overview of the field of magnetic nanotechnology. The book contains 12 major chapters written by 24 authors from eight different countries. ... the most likely reader of this book will be an engineer in a university or in industry."
