Abstract
In EPR studies on Fe(III) ions in CdGa2S4 crystals, in accordance with the two different Ga sites two paramagnetic centers could be detected which differ widely in their axial parameter D. An investigation of the crystal field allowed a unique site assignment. A comparison with the Fe(III) resonances in CuGaS2 and AgGaS2 does show that the superposition model of Newman and Urban cannot be applied to CdGa2S4 with similar parameters as in the chalcopyrite structures. - A characteristic twinning could be revealed, similar to the “reversed cubic structure” in sphalerite.
