<p> Oxygen deficient SrTiO3-x with x = 0.28(2) was prepared in single crystal form
and found to have a perovskite structure with a small tetragonal distortion. The structure
was studied by powder and single crystal X-ray diffraction and electron diffraction. No
long range order of the oxygen vacancies could be detected. The transport studies show
that SrTiO2.72 is a metallic conductor. </p> <p> Some new K2NiF4 - type compounds, PrSrVO4, SmSrVO4, EuSrVO4 and
PrSrGaO4, were prepared and studied by powder diffraction methods. The crystal
structures of LaSrVO4, CeSrVO4, PrSrVO4 and NdSrVO4 were refined from powder
neutron diffraction data. Powder X-ray diffraction data for all the new compounds above
and for EuSrAlO4 are presented here. </p> <p> Magnetic susceptibilities are reported for SrTiO2.72 which exhibits metal-like
Pauli-paramagnetism, PrSrGaO4, NdSrGaO4, EuSrAlO4 and LnSrVO4 where Ln = La,
Ce, Pr and Nd. </p> / Thesis / Master of Science (MSc)
