CRYSTAL CHEMISTRY STUDIES.
Abstract
Research has been concerned with (1) the systematic study of the rare earth - rhenium oxide systems in a search for new ferrimagnetic compounds. Several ternary phase areas have been determined and work on the crystal structure and composition of these phases is in progress; (2) Six intermediate phases have been isolated in the system V2O3-V2O5. Four of these phases have magnetic and electrical phase transitions; (3) Work has been started with the Sm-O system. SmO has been prepared by hydrogen reduction of Sm2O3. (4) The site preference (tetrahedral, octahedral) of Co and Ni ions in glass has been redetermined. While the Ni(2+)/Ni(3+) ratio increases with oxygen pressure, no measurable changes in the Cr(2+)/Cr(3+) ratio have been found. (Author)
