Electron spin-lattice relaxation of Cu(II) in Zn(II)-bis(diethyl-diselenocarbamate) single crystals

Abstract

Using the pulse saturation method the spin-lattice relaxation rate T1 -1 for Cu(II) in Zn(II)-bis(diethyl-diselenocarbamate) was measured in the temperature range 1.5 < T < 33 K. From the T-dependence of T1 -1 the Debye temperature of the host crystal was obtained. The angular dependence of T1 -1 as well as the influence of the hyperfine interaction on T1 -1 are discussed. © 1974.
