NEW BOOKS ON MAGNETISM

MONDO Magnets:40 Attractive (And Repulsive) Devices & Demonstrations - by Fred Jeffers

Review by R.D. Mel Gomez,
Prof. of Electrical and Computer Engineering
University of Maryland, College Park

When they say cereals are iron-fortified, I never expected that my breakfast flakes could be attracted by magnets! Fred Jeffers, in his new book Mondo Magnets, describes procedures for finding magnetism in objects we do not normally regard as magnetic. He continues with thirty nine more experiments that exhibit some fascinating and often counter-intuitive properties of magnetism. In one other experiment, he shows how a material that is magnetized by a permanent magnet can actually be more attractive than the magnet itself. In yet another segment, he shows the principle of gears with magnetic rather than mechanical teeth.

Working in the product research industry for nearly 40 years has given Fred a deep intuitive feel for magnetism which he shares to the laymen and experts alike. He gives simplified explanations on many experiments in sections called the “science behind it”. As a result, the book is a valuable resource for those who build demonstrations for education and entertainment. With the exception of magnetotactic bacteria, most of the materials are readily available from a hardware or grocery store, and a few specialized items are conveniently provided with their sources. The experiments all work, which undoubtedly were tested several times over when Fred took them on the road as an IEEE Distinguished Lecturer in 1999.

For those who know magnetism well enough, this book provides a plethora of activities that illustrate the concepts of magnetostatics, magnetic propulsion, levitation, magnetic permeability and image charges, Curie temperature, anisotropy, diamagnetism, magnetostriction, magnetic recording and many more. Indeed, I found myself scribbling calculations to quantify the reasoning behind Fred’s qualitative explanations. It was fun.

This third volume of Spin Dynamics in Confined Magnetic Structures addresses central aspects of spin-dynamic phenomena on a tutorial level. Researchers will find a comprehensive compilation of the current work in the field. Introductory chapters help newcomers to understand the basic concepts. The more advanced chapters give the current state-of-the-art of spin dynamic issues ranging from the femtosecond to the microsecond regime. This volume concentrates on new experimental techniques such as ferromagnetic-resonance-force microscopy and two-photon photoemission, as well as on aspects of precessional switching, spin-wave excitation, vortex dynamics, spin relaxation, domain-wall dynamics in nanowires and their applications to magnetic logic devices. One chapter is devoted to the very hot subject of spin-transfer torque, combining electronic transport and micromagnetics. The comprehensive presentation makes it a very timely and valuable resource for every researcher working in the field of magnetism.

Contents : Precessional Switching of Thin Nanomagnets with Uniaxial Anisotropy. ▪ Spin-Wave Excitations in Finite Rectangular Elements. ▪ Ferromagnetic Resonance Force Microscopy. ▪ Vortex Dynamics. ▪ Domain-Wall Dynamics in Nanowires and Nanostrips. ▪ Domain-Wall Dynamics in Magnetic Logic Devices. ▪ Spin Transfer Torque and Dynamics. ▪ Spin and Energy Relaxation of Hot Electrons at GaAs Surfaces.
