Abstract The Cr3+ EPR spectra of YAG type crystals normally consist of four peaks whose positions are dependent on the axial zero-field splitting D with axis along a 〈111〉 direction and angle ϑ between that direction and the applied field H 0. In LLGG only three principal peaks are observed with zero-field axis nearly along x, y or z. This anomaly is attributed to the relatively small size of Cr3+ compared to Lu3+ which it displaces in an octahedral site. D varies slightly for the different zero-field axes: 0.480 cm−1 along x, 0.429 cm−1 along y and 0.470 cm−1 along z. The spectroscopic splitting factor g=1.978±0.001 is essentially isotropic and independent of axes within the experimental error.
