Abstract
In this paper, we present detailed studies of the EPR spectra of Cu2+ ions in single crystals of ZnSeO4·6H2O. We describe the spectrum with a rhombic spin Hamiltonian with the following parameters: gz=2.427; gy=2.095; gx=2.097; A 65z =138.4·10−4 cm−1; A 65x =22.3·10−4 cm−1. We studied spin-lattice relaxation in the temperature range 4–300 K at the frequency v≈9.3 GHz. The measured spin-lattice relaxation rate for the orientation H∥L4 is described well at T<5 K by a linear dependence, while at T>5 K it is described by the sum of three exponentials:
.We discuss possible reasons for the exponential dependence of T −11 for the Raman process.
