Rezumat

A theory of thermodynamic properties of a spin density wave (SDW) in a quasi-twodimensional system (with a preset impurity concentration x) is constructed. We choose an anisotropic dispersion relation for the electron energy and assume that external magnetic field H has an arbitrary direction relative to magnetic moment MQ. The phase diagram ( ) is constructed. The effect of the magnetic field on magnetic transition temperature TM is analyzed for HzH σ = 0. The effect of anisotropy of the electron energy spectrum on the investigated physical quantities is also analyzed.
