Magnetic anisotropy in CsGd(MoO4)2probed by EPR spectroscopy.

Here we report electron paramagnetic resonance (EPR) study of rare-earth paramagnet CsGd(MoO4)2. Multifrequency EPR measurements allowed us to directly probe the splitting of the lowest8S7/2multiplet of Gd3+ion and revealed the rhombic type of single-ion anisotropy. An easy-axis anisotropy approximation with a rhombic distortion of the Gd3+local environment describes obtained EPR spectra and yield energies of8S7/2splitting. Within this model, we discuss the configuration of the lowest Gd3+multiplet, its zero-field splitting, and the anisotropy of magnetic properties in CsGd(MoO4)2. We argue that the zero-field splitting of8S7/2induces a multiple structure of EPR spectra in CsGd(MoO4)2. © 2020 IOP Publishing Ltd.
