THE PEAK IN TRM OF A FINE PARTICLE SYSTEM

In this paper we report on the peak phenomena in the thermoremanent magnetisation (TRM) of a fine particle system. From a generalised model based on the solution of the master equation we calculate the effects of the time dependence of magnetisation during the period of switching off the cooling field. For a constant value of field reduction with time, the calculation show that the reduction in the magnetisation is constant and no peak is predicted. However for a non-linear field reduction with time a peak in the TRM is predicted.
