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 distribution. Then the phase diagrams are constructed on the crystal field (Δ …
