Phase transition in n-layer ising lattices with impurities

Abstract

The phase transition temperature are calculated for two kinds of models for n-layer Ising lattices. One is diluted by non-magnetic impurities and the other consists of two kinds of magnetic infstances. When the number of layers n increases, the transition temperature calculated by the high temperature series expansion increases monotonically. In the first model the critical concentration pc decreases with n. Although a single layer lattice with p
