Our results indicate significant differences between the EPR spectra of Cu2+ ions in the tetragonal and orthorhombic phase. It is concluded that in the tetragonal phase, the Cu2+ complex has axial symmetry. Furthermore, at low temperatures the observed EPR signal is associated with superexchange interaction between Eu2+ ions across oxygen bridges. © 1991.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 4</style></notes></record></records></xml>
