An Integrated Model of Magnetic Hysteresis, the Magnetomechanical Effect, and the Barkhausen Effect

This article reviews the ferromagnetic hysteresis, magnetomechanical, and Barkhausen properties of magnetic materials presents an integrated model to describe these effects underlying mechanisms that cause effects. Hysteretic ferromagnets, such as permeability, coercivity, remanence, hysteresis loss are known be sensitive external factors including applied stress, temperature, heat treatment, internal like residual strain, microstructure, grain size, anisotropy presence precipitates a second phase, iron carbide in steels. It thus becomes imperative characterize effect on parameters. Currently, several models Preisach, Stoner-Wohlfarth, Jiles-Atherton used materials. We review here quasistatic which describes terms domain wall motion enabling connection made physical response material. has been extended include magnetomechanical Theoretical work presented provides conceptual framework linking together property measurements with parameters structure
