Essay

Object: two-dimensional spin models of continuous symmetry with disorder. Aim: investigation of the pecularities of the behaviour of the models considered due to disorder. Methods: functional integration method and Monte Carlo simulations. Results: behaviour of the spin-spin correlation function and magnetization, interaction between impurities and spin vortices, critical temperarure reduction. Application: theory of phase transitions.
