摘要：

The influence of thermal fluctuations on the hysteresis curve of particle assemblies is studied by starting from a general master equation approach. The relaxation process and the superparamagnetic behaviour is investigated within the discrete orientation approximation for assemblies of particles with aligned and randomly oriented anisotropy axes.
