Dynamic hysteresis in an anisotropic superparamagnet
Abstract
Dynamic magnetic hysteresis in a single-domain uniaxial particle was studied on the basis of the kinetic approach for the base of an arbitrary angle between the easy magnetization axis and an applied field. Hysteresis loops and absorbed power were calculated, and the dependences of the cyclic magnetization process on the temperature, particle characteristics, and the frequency and amplitude of the magnetizing field were analyzed.
