We described ultrafast spin motion modes for non-Heisenberg magnets that allow quantum spin reduction effects. We predicted a new magneto-optical effect in the materials with strong quantum spin reduction, which can lead to picosecond longitudinal spin reorientation. We studied coupled dynamics and relaxation of the spin and orbital degrees of freedom and predicted new types of excitations with ultrafast dynamics. We also studied the static and dynamic properties of promising materials - arrays of magnetic nanoparticles. We predicted new mesoscopic magnetic inhomogeneities in an antiferromagnet with dislocation loop. We also predicted the existence of surface modes localized at the boundaries of magnetic dot arrays.
