A Single, Comprehensive Theory: Deciphering Hysteresis

Abstract

Volume 21, Issue 1 of London LJP Journals Press 449U, Compilation 1.0 Long explored, but as of yet unresolved, is the issue of the mathematical description of the hysteresis loop of ferromagnetic materials. Particularly popular models are the Jiles-Atherton model of ferromagnetic phenomenology and the Preisach model of generic hysteresis characteristics. However, they can only partially explain hysteresis. Due to hysteresis loss, the eddy current heats up nanomagnetic materials. Hysteresis is currently more important to investigate due to nanomagnetic features, yet it can only be explained by magnetic domains and their variations. This study first illustrates the ferromagnetic hysteresis loop opening using a trigonometric model. Finally, it is mentioned that it is confirmed.
