HIGH-FIELD EPR OF ZN1-XCRXTE

High magnetic field electron paramagnetic resonance experiments have b een performed on Zn1-xCrxTe covering the energy range 1-7 cm(-1) in fi elds up to 20 T at T = 1.2 K. The static magnetic field was oriented a long the (100), (110) and (111) crystallographic axes of the sample. P ronounced absorption lines for intra-chromium transitions have been ob served for these different orientations, revealing a strong anisotropy due to a static Jahn-Teller distortion. The measured low energy level structure of the Cr++ ion can be described by a cubic crystal field m odel including this distortion of the Cr centers.
