EPR of Nd3+ Ions in the Common Position in a Cubic Single Crystal KZnF3

The electron paramagnetic resonance (EPR) spectrum of 24 magnetically nonequivalent Nd3+ centers has been found and studied in the perovskite-type crystal KZnF3 for the first time. The problem of attributing EPR spectra of magnetically nonequivalent centers with S = 1/2 in crystals with the cubic symmetry was solved in the general form. The parameters of the spin Hamiltonian were determined.
