A new definition of the hysteron in hybrid vector hysteresis model

A new definition of hysteron is presented in this paper based on classical Preisach and Stoner-Wohlfarth(S-W) hysteresis model. The magnetic properties and the determining rule of magnetization direction of ellipse magnetic particles with single domain and uniaxial anisotropy are analyzed qualitatively via studying the variation of energy density. The critical surface equations of the hysterons of anisotropy and isotropy materials are defined using the equipotential curves of vector field produced by magnetic particles, so that the hysteron is a closed region surrounded by equipotential curves. The determination of magnetization direction of hysteron is discussed at later chapter of the paper. The hysteron defined in this paper is consistent with the second principle of thermodynamics and Mandelung rules, and has loss property and deletion property.
