The EPR spectrum of the copper Cu2+ impurity magnetic center in a single crystal of zinc-gallium spinel ZnGa2O4 has been studied in a wide temperature range T = 4.2–300 K. The EPR spectrum exhibits properties similar to those for off-center ions, which contribute to the formation of a multiminimum crystal field potential in the immediate environment of the Yang–Teller Cu2+ copper complex in a single crystal. A study of the temperature dependence of the integral intensity of the EPR spectrum lines has been carried out. The height of the potential barrier that separates the equivalent potential pits containing Cu2+ copper ions has been determined. Cu2+ ions occupy structurally unequal centers in the elementary crystal lattice.
