Hysteresis in Magnetism: For Physicists, Materials Scientists, and Engineers (Electromagnetism) 1st Edition by Giorgio Bertotti (PDF)

Description

This book provides a comprehensive treatment of the physics of hysteresis in magnetism and of the mathematical tools used to describe it. Hysteresis in Magnetism discusses from a unified viewpoint the relationsof hysteresis to Maxwells equations, equilibrium and non-equilibrium thermodynamics, non-linear system dynamics, micromagnetics, and domain theory. These aspects are then applied to the interpretation of magnetization reversal mechanisms: coherent rotation and switching in magnetic particles, stochastic domain wall motion and the Barkhausen effect, coercivity mechanisms and magnetic viscosity, rate-dependent hysteresis and eddy-current losses. The book emphasizes the connection between basic physical ideas and phenomenological models of interest to applications, and, in particular, to the conceptual path going from Maxwells equations and thermodynamics to micromagnetics and to Preisach hysteresis modeling.The reader will get insight into the importance and role of hysteresis in magnetism; In particular, he will learn:which are the fingerprints of hysteresis in magnetismwhich are the situations in which hysteresis may appearhow to describe mathematically these situationshow to apply these descriptions to magnetic materialshow to interpret and predict magnetic hysteresis phenomena observed experimentally

⭐I studied solid state magnetics in grad school, but without the benefit of a text covering in detail the theoretical underpinnings of the subject. Last year, I decided to refresh my memory on many of the topics in this book, and was pleased by both the breadth and depth of material present.The book starts out with an explanation of what hysteresis is, and how it pertains to magnetism, and then moves on to coper topics such as Maxwell’s equations in magnetic media, anisotropy, micromagnetics, magnetic domains and domain walls, the magnetization process, eddy currents and loss mechanisms, and finally closes with a discussion of the Preisach model.All in all, a good reference to have, for those in the field of solid state magnetics.
