Abstract: We study the thermodynamic properties of spin-12 anisotropic Heisenberg model with Dzyaloshinsky-Moriya (DM) interaction using the Oguchi approximation. Although the theory is developed for lattices with general coordination number z, we treat in detail the model in the simple cubic lattice (z=6), where the critical and tricritical behavior of the thermodynamic properties are analysed as a function of DM parameter.
