Аннотация: It is shown that frustrations caused by additional spins result in a greater variety of phases with commensurate and incommensurate periods as well as in the appearance of nonperiodic phases. It is established that a single-e modulated phase is unstable against zero-point motions. As a result, a disordered state with zero magnetization at a site can exist in a wide range of values of the frustration parameters.

Аннотация: Magnetic states and phase transitions of the layered triangular antiferromagnets in an applied field are studied. It is shown that in compounds like VBr2 and VCl2 quantum effects change the ground state structure and cause successive phase transitions as the magnetic field increases. Coplanar structures of different spin configuration are realized far from the saturation field and a noncoplanar structure of umbrella-type configuration is realized near this field. The ground-state phase diagram is constructed, and a finite region of fields where the collinear phase is also possible is indicated.
