摘要: The molecular-based magnetic materials AFeIIFeIII (C2O4)3 have a honeycomb structure in which FeII (S = 2) and FeIII 5/2) occupy sites alternately. They can be described as mixed spin-2 spin-5/2 Ising model with ferrimagnetic interlayer coupling. influences of the transverse field on internal energy specific heat system been studied numerically by using effective-field theory self-spin correlations differential operator technique.
