Spin-1 Blume–Capel model with random crystal field effects

Albayrak, Erhan - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 4, pp. 552-557

The random-crystal field spin-1 Blume–Capel model is investigated by the lowest approximation of the cluster-variation method which is identical to the mean-field approximation. The crystal field is either turned on randomly with probability p or turned off with q=1−p in a bimodal...
