摘要：

Using Monte Carlo simulation (MCs), we study thermal and hysteresis behaviors of a mixed spin-1/2 and spin-1 using Blume-Emery Griffiths model. Starting from the spin Hamiltonian which describes the system, the influence of the crystal-field and biquadratic exchange interaction on the critical behaviors has been investigated. Critical exponents were calculated and compared with those of the 3D Ising model. (C) 2017 Published by Elsevier Ltd.
