A magnetic bilayer system with spin S= 1/2, the coordination number z= 5 and anisotropic
Heisenberg ferromagnetic interactions, is studied by the Cluster Variational Method in the …

Motivated by the unusual evolution of magnetic phases in stoichiometric and Co-doped
YbRh 2 Si 2, we study Heisenberg models with competing ferromagnetic and …

The critical and hysteresis behaviors of the ferromagnetic mixed-spin system consisting of
two sublattices A and B with two types of spins SA= 3 2 and SB= 1 2 described by …

The hysteresis behaviors of anisotropic S-1 Heisenberg model have been studied within the
effective field theory with two spin cluster. After giving the phase diagrams, the effect of the …

We developed a technique to determine suitable spin models for small embedded clusters
of arbitrary geometry by combining the spin-cluster expansion with the relativistic disordered …

The bicritical properties of the three-dimensional classical anisotropic Heisenberg model in
a crystal field are investigated through extensive Monte Carlo simulations on a simple cubic …

In this paper we are investigating the magnetic behavior of the double-layer thin film in the
extended Heisenberg model, with long-range dipolar interaction, taking into account the …

In the last few years there has been significant interest in the field of thin films, due to
numerous specific phenomena related to the low dimension of these systems, and to the …

Abstract Extensive Monte Carlo simulations are used to locate the bicritical point of the
ferromagnetic anisotropic Heisenberg model on a simple cubic lattice in the presence of a …

We have studied the magnetization reversal process in FM/AFM bilayer structures through of
spin dynamics simulation. It has been observed that the magnetization behavior is different …
