PHASE TRANSITION PROPERTIES OF A TWO-COMPONENT FINITE MAGNETIC SUPERLATTICE

doi:10.1088/1009-1963/9/9/002

Abstract

Abstract We study an (l,n) finite superlattice, which consists of two alternative magnetic materials(components) of l and n atomic layers, respectively. Based on the Ising model, we examine the phase transition properties of the magnetic superlattice. By transfer matrix method we derive the equation for Curie temperature of the superlattice. Numerical results are obtained for the dependence of Curie temperature on the thickness and exchange constants of the superlattice.

Keywords: phase transitions finite magnetic superlattice Ising model transfer matrix method.
