The static and dynamic properties of an anisotropic ferrimagnet, which has sublattices with S = 1 and σ = 1/2 and is characterized by a non-Heisenberg (spin bilinear or biquadratic) exchange interaction for the sublattice with S = 1, are studied. Th

The effect of single-ion anisotropy on the phase states and dynamic properties of a non-Heisenberg magnet with S = 1 is investigated in the mean field approximation. It is shown that, in contrast to the isotropic model, the inclusion of single-ion an

Phase states of an isotropic non-Heisenberg magnet with a magnetic ion spin of 3/2 on a triangular lattice are studied. It is shown that both dipole (ferro- and antiferromagnetic) and tensor (nematic and antinematic) phases can be implemented in the

Static and dynamic properties of a two-sublattice non-Heisenberg magnet with complex interion anisotropy of both bilinear and biquadratic exchange interactions are investigated. Existence conditions are found for phases with the dipole order paramete

The Ising model with the frustrated exchange interaction for strongly anisotropic antiferromagnetic ultrathin film is investigated in the mean field approximation at low temperatures. It is shown that a spatially inhomogeneous state can be accomplish

A phase diagram of a magnetic material with the spin S = 2 is obtained including all allowed spin invariants for the isotropic exchange interaction at an arbitrary relation between exchange constants. New phases with two-sublattice structure and biax

The influence of the anisotropic exchange interaction on the phase states of a non-Heisenberg ferromagnet with a magnetic-ion spin S = 1 is studied. It is shown that, depending on the relationships between the parameters of anisotropic exchange inter

The investigations performed in this work have demonstrated that an easy-axis frustrated non-Heisenberg magnet can contain homogeneous phases with the vector (ferromagnetic) and tensor (nematic) orderings, as well as a spatially inhomogeneous phase o
