Annotatsiya
Based on the results of investigations of the angular dependence of EPR spectra and the Zeeman effect above and below the structural phase transition, it has been established that magnetically nonequivalent centers in the disymmetrical phase of CsDy (MoO4)2 arise. Possible structural changes in the crystal, caused by the phase transition, are discussed.
