Abstract : The ferroelectric and structural properties of HfO2 compounds, using high purity (99.9%) HfO2 were investigated. The compounds studied were CaHfO3, SrHfO3, and (Pb,Ba)HfO3 solid solutions. Dielectric measurements were made between room temperature and 300C. Hysteresis loop measurements were made at liquid nitrogen temperature, room temperature and at approximately 120C. The compositions and crystalline structures formed were identified by x-ray diffraction techniques. (Author)
