Abstract
BaHfO3 is prepared by sintering a mixture of BaCO3 and HfO2 giving the same heat treatments as for YBa2Cu3O7-delta (YBCO). X-ray diffraction analysis confirms the formation of cubic BaHfO3 along with some unrea cted HfO2. A Ta-181 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 constant lambda congruent to 0.26 ns is unusually large and temperature independent.
