Magnetic structure of the crystal CsDy(MoO4)2

The energy of the ordered state of the rare-earth subsystem of CsDy(MoO4)2, with a unit cell containing two magnetically inequivalent rare-earth ions, is calculated in the dipole approximation. The magnetic configuration of the rare-earth ions corresponding to the ground state of the magnetically ordered phase is determined. The field dependence of the magnetizations Ma, Mb, and Mc at T=0 K is calculated. The phase transitions caused by an external magnetic field are analyzed. The values of the equivalent G factors obtained from the calculated magnetization curves agree satisfactorily with the values determined from the experimental data on the heat capacity and magnetic susceptibility.
