Abstract
Surface phase diagrams of a spin-one monolayer on a semi-infinite spin- 1 2 ferromagnet are investigated by using a version of the effective-field theory. In particular, the effects of the surface biquadratic exchange interaction on the surface phase diagram are discussed. Some characteristic features of the surface magnetism are found, such as the surface tricritical behavior and the surface reentrant phenomena.
