Abstract

In this paper, we present a model for the breathing crystal field of spin-crossover solids. Using Monte Carlo simulation, we have systematically studied the thermal transition of spin-crossover solids for local random fields with different statistical characteristics. It is found that the breathing of crystal field provokes the broadening of the hysteresis loop, but for strong colored fluctuations its power spectrum is diminished and the width of the hysteresis loop approaches again to the deterministic one.
