Vernadsky University popup.description2 It is obtained for the first time phase diagrams of an alloy that allow for magnetoelastic interaction and monolayer of that alloy. It is shown for the first time that in a collinear antiferromagnet with large one-ion anisotropy of the easy plane type it is possible implementation of a phase analogous to the "supersolid" state in 4He. It is determined for the first time all the spin states of an isotropic non-Heisenberg s=3/2 magnet allowing for all spin invariants. It is studied for the first time the effect of quantum reduction of spin in a ferromagnet with an anisotropic sub-grating.
