Despite several decades of active experimental and theoretical studies of rare-earth orthoferrites, the mechanism of the formation of specific magnetic, magnetoelastic, optical, and magneto-optical properties remains a subject of discussion. This pap

The concept of charge-transfer (CT) transitions in ferrites is based on the cluster approach and takes into account the relevant interactions as the low-symmetry crystal field, spin-orbital, Zeeman, exchange and exchange-relativistic interactions. Fo

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$_{1-x}$Cr$_x$O$_3$ with a non-magnetic R-ion (R = La , Y, Lu), i.e. s

We consider highly anisotropic 2D quantum s = 1/2 (pseudo)magnetic system which is equivalent to the frequently used system of charged hard-core bosons on a square lattice. In the continuous quasi-classical approximation, the types of localized excit

We have applied a generalized mean-field approach and quantum Monte-Carlo technique for the model 2D S = 1 (pseudo)spin system to find the ground state phase with its evolution under application of the (pseudo)magnetic field. The comparison of the tw

We report new results of a 57Fe M\"ossbauer study of multiferroic 3R-AgFeO2 powder samples performed in a wide temperature range, including two points, TN1 ~ 14 K and TN2 ~ 9 K, of magnetic phase transitions. At the intermediate temperature range, TN
