Abstract:

EPR spectra between 9.7 K and room temperature (RT) were taken for EuBa2Cu3O7-δ in tetragonal and orthorhombic phases. 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.
