Abstract
The spin subsystem of copper oxides within the model of polar singlet-tripl et Jahn-Teller centers is described by the Hamiltonian of a singlet-triplet magnet with multiparametric (non)collinear spin arrangements. Using the mo dified mean-field approximation we analyze the conditions of an appearance of the non-collinear phase. Certain static and dynamic properties of the ne w phase are considered.
