Abstract
EPR spectra attributed to Cu2+ paramagnetic ions have been observed be low T = 130 K, in the low-temperature ferroelectric phase of as grown Rb2ZnCl4 single crystals doped in the melt with CuCl2. Their concentra tion is strongly increased by subsequent X- or gamma-ray irradiation a t room temperature. The analysis of the EPR spectra shows the Cu2+ ion s to be situated at the distorted, tetrahedrally coordinated Zn2+ site s.
