Abstract

The effect of an external magnetic field on the phase transitions and the thermodynamic and magnetic properties of the three-dimensional antiferromagnetic Ising model on a body-centered cubic lattice has been studied using a replica algorithm of the Monte Carlo method, taking into account the interactions of next nearest neighbors. A phase diagram of the dependence of the critical temperature on an external magnetic field has been built. It is shown that a second-order phase transition is observed in the magnetic field range under consideration.

摘要

考虑了相互作用，研究了外部磁场对体心立方晶格的三维反铁磁伊辛模型的相变以及热力学和磁性的影响下一个最近的邻居。已经建立了临界温度对外部磁场的依赖性的相图。结果表明，在所考虑的磁场范围内观察到了二级相变。
