Abstract

BaHfO3 is prepared by sintering a mixture of BaCO3 and HfO2 giving the same heat treatments as for YBa2Cu3O7−δ (YBCO). X-ray diffraction analysis confirms the formation of cubic BaHfO3 along with some unreacted HfO2. A181Ta TDPAC study of the sample, prepared using neutron-irradiated HfO2 and BaCO3, shows a relaxation process to be present in the sample. The value of the relaxation constantλ≅0.26 ns is unusually large and temperature independent.
