Tetragonal Cr5+ impurity centre in single crystals of the perovskite SrTiO3. After careful analyses we came to the conclusion that this centre is an off-centre system and no Jahn-Teller impurity. From the previous stress experiments in EPR we calculated the linear stress coupling tensor as β = 3.56×10-30 m3, which is in agreement with other stress coupling tensors of off-centre systems in SrTiO3 as well as BaTiO3.
