Abstract: We study surface magnetism in a semi-infinite alternating magnetic superlattice. The spin-1/2 Ising model with alternating exchange constants JA and JB is used in the mean-field approximation. The effects of surface modification on the magnetic properties are expressed in terms of two types of determinants. The numerical results for the critical exchange constants and the surface transition temperatures are obtained for two types of surface modification. © 1992 The American Physical Society.
