摘要

The EPR spectrum of the Gd3+ ion in the elpasolite-type Rb2NaYF6 crystal has been discovered and studied. It is established that the paramagnetic Gd3+ center has cubic symmetry at T = 295 K. The parameters of the corresponding spin Hamiltonians are calculated. A structural model of the complex is proposed. The experimental results are analyzed by comparison with those for the paramagnetic Gd3+ ion in other lattices.
