چکیده انگلیسی
MnIIFeIII bimetallic oxalates are described by a spin-5/2 Blume-Capel (BC) model on a layered honeycomb structure. The effects of the interlayer coupling, the single-ion anisotropy and the oscillating magnetic field on the dynamic critical temperature of the compounds are studied by a effective-field method based on Glauber-type stochastic dynamic. Dynamic phase diagrams are presented in the DAâJ1-TâJ1 and TâJ1-h0âJ1 planes, and the first-order phase transition lines and the critical end point are found. Compensated magnetization regions have also been plotted and the compounds exhibit an uncompensated magnetization in the antiferromagnetic phase. In particular, a two-compensation-temperature phenomenon has also been observed in MnIIFeIII bimetallic oxalates.
