摘要：

Magnetic properties of the bond and crystal field dilution spin-3/2 Blume-Capel model in an external magnetic field (h) on simple cubic lattice are studied by using the effective field theory. In the m-T plane, the degeneracy of the magnetization (m) is affected by the concentration of bond or crystal field dilution at low temperature (T). The magnetization curves can appear to fluctuate in certain regions of negative crystal field. In the m-h plane, the initial magnetization curve has an irregular behavior due to the introduction of bond dilution. The crystal field dilution has the influence on the process of magnetic domain displacement. In the chi-h plane, there exists one susceptibility (chi) shoulder and one step for different negative crystal field. The susceptibility curve takes on the feature of multi-peaks distribution under bond and crystal field dilution conditions. (c) 2012 Elsevier B.V. All rights reserved.
