摘要:
Within the framework of the Monte Carlo simulation, we have studied the critical and the compensation behaviors of a mixed spins S = 5/2 and sigma = 2 (AFe(II)Fe(III)(C2O4)(3)) Ising system on a nano-graphene layer. The effects of the crystal field, the four spin interaction, the biquadratic exchange interaction and the external magnetic field on the critical behavior, the magnetic properties and the blocking temperature have been studied in this paper.
