Jahn-Teller Effect of Cu2+ ions in a Zinc Selenate Hexahydrate Single Crystal

摘要

X- and Q-band studies of Cu2+ and Mn2+ doped ZnSeO4·6H2O single crystals in the temperature range of 4.2-300 K are carried out. Experimental data on EPR, spin-lattice relaxation time and optical absorption spectra are explained in the frame of the Jahn-Teller Effect of the Cu2+ ion under the low- symmetry deformation of the nearest environment of the Cu2+ ion.
