摘要

A two-dimensional model of antiferromagnetic systems near the phase transitions of spin density waves has been considered taking into account the superconducting phase. Particular attention has been paid to the study of the influence of nonlinear effects, in particular, the interaction constant of the order parameter fluctuations, on the phase transitions arising in the system.
