Magnetic Concentration Phase Transitions in Ultrathin Films

摘要：

　　Modeling study of magnetic and concentration phase transition in ultrathin films of diluted magnet has been carried out under approximation of random interaction between atomic magnetic moments of nearest neighbors and within the framework of Ising model.The dependence of Curie temperature on concentration of magnetic atoms was formed.It is shown that with increasing of thickness of ultrathin film the critical concentration of transition from unordered to ordered magnetic state decreases down to the value equal to the percolation threshold.
