Reentrance Phenomenon of a Mixed Spin Ising Model

Full Text PDF

Abstract:

A reentrant magnetic phase transition in molecular based magnet AFeIIFeIII(C2O4)3[A=N(n-CnH2n+1)4, n=3-5] is investigated by the use of Mean-Field Theory (MFT) for a mixed spin-2 and spin-5/2 Ising system on a simple cubic lattice. It is found that a double-entrant ferrimagnetic behaviour in the mixed-spin system depends on the negative values of the anisotropies in the order-disorder system for the two sublattices of the mixture. It is shown using numerical calculations that this phenomenon is strongly affected by the magnetic anisotropy and lattice disorder.
