Abstract
Magnetizations and compensation behaviors of the bond and crystal field dilution mixed spin- 1 2 and spin-1 Blume–Capel model in an external magnetic field are investigated by using the effective field theory on simple cubic lattice. Magnetization and compensation point dependences of temperature or external magnetic field for different parameters are calculated. We find a new magnetic compensation behavior in M− H space and define a compensation magnetic field H k . The crystal field and magnetic field have the effect of changing the compensation temperature in M− T space, while the crystal field and bond dilution can affect the compensation magnetic field. There is a magnetization plateau for H< H k at low temperatures. The magnetic compensation behaviors are not revealed in previous works and predicted by Nèel theory of ferrimagnetism.
