Abstract
The effects of the Dzyaloshinskii-Moriya (DM) interaction on the magne tic properties of a spin-1/2 anisotropic Heisenberg system are investi gated by using a two-spin cluster mean-field (MFA) procedure. We find for the easy direction model (i.e., D = D z; where D is the DM vector coupling) a variety of interesting phenomena resulting from a competit ion between exchange and DM interactions.
