Abstract
For pt.I see ibid., vol.5, p.2779-92 (1993). A comprehensive study of the remanence curve properties of an assembly of noninteracting single-domain particles with cubic magnetocrystalline anisotropy has been performed. The theoretical calculations presented represent an extension of the zero-temperature analysis of Joffe and Heuberger to include the effects of thermally activated magnetization reversal and particle size distribution. The numerical validity of these computations is completed through the analysis of interaction-sensitive Henkel plots, which confirm the non-interacting nature of the independently calculated remanence curves. The model system shows behaviour with intuition and analogous to similar models for the uniaxial case, with the exception of the expected increase in maximum remanence and decrease in energy barrier, i.e. remanence coercivity.
