Magnetic materials can support propagating waves of magnetization; since these are oscillations in the magnetostatic properties of the material, they are called magnetostatic waves (sometimes magnons or magnetic polarons ). Under the proper circumstances these waves can exhibit, either dispersive or nondispersive, isotropic or anisotropic propagation, nonreciprocity, frequency-selective nonlinearities, soliton propagation, and chaotic behavior. This rich variety of behavior has led to a number of proposed applications in microwave and optical signal processing.

Some ferromagnetic materials with localized magnetic moments have become a hot topic of modern solid state physics because of their potential applications, e.g. in spintronic devices. The magnetic systems of interest comprise diluted magnetic semiconductors and half-metallic ferromagnets. Like conventional concentrated local-moment systems, they are characterized by an exchange interaction between localized magnetic moments and quasi-free charge carriers. The current research on local-moment ferromagnetism is reviewed in a tutorial style by leading experts in this field. Experimentalists...

The first part of this state-of-the-art book conveys the fundamentals of magnetism for atoms and bulk-like solid-state systems, providing a basis for understanding new phenomena which exclusively occur in low-dimensional systems as the giant magneto resistance. This wide field is discussed in the second part. Suitable for graduate students in physical and materials sciences, the book includes numerous examples, exercises, and references.

For the past seventy years, ferrites (magnetic ceramics) have been prized for a range of properties that has no equivalent in the existing metal magnetic materials. They have contributed to many important advances in electronics and new high-performance products are appearing all the time. Ferrite technology has produced greater progress in the past 15 years since the first edition was published. Many of the semiconductor and IC technology responsible for the computer and Internet explosion would not have been possible without the magnetic materials technology needed for powering and...

Food safety awareness is at an all time high, new and emerging threats to the food supply are being recognized, and consumers are eating more and more meals prepared outside of the home. Accordingly, retail and foodservice establishments, as well as food producers at all levels of the food production chain, have a growing responsibility to ensure that proper food safety and sanitation practices are followed, thereby, safeguarding the health of their guests and customers.

Achieving food safety success in this changing environment requires going beyond traditional training,...
