Single-doublet model of spin reorientation
Evgenii Vasinovich, Alexander Moskvin
A simple theoretical model is developed to describe spin reorientation (SR) transitions in rare-earth orthoferrites and orthochromites RFeO3 and RCrO3. Within a ``single-doublet''…

Features of magnetization and spin reorientation in weak ferrimagnets of the YFeCrO type
Alexander Moskvin, Evgenii Vasinovich
A brief critical review is given of the 50-year history of experimental and theoretical studies of the magnetic properties of a new promising class of weak ferrimagnets such as RFe…

Superconductivity in model cuprate as an S=1 pseudomagnon condensation
E. V. Vasinovich, A. S. Moskvin, Yu. D. Panov
We make use of the S=1 pseudospin formalism to describe the charge degree of freedom in a model high- cuprate with the on-site Hilbert space reduced to the three effective val…
