Abstract :
AC magnetization curves of a Stoner-Wohlfarth model system consisting of noninteracting uniaxial single-domain particles are described by Fourier expansion. Two types of hysteresis curves are considered-the first one with a magnetizing field changed in a sine periodical way, and the second one with the magnetization of the system changed in a sine periodical way.
