Ytterbium cobalt gallium oxide, YbCoGaO4, as grown by the floating zone technique

Abstract

Single crystals of YbCoGaO4 have been grown for the first time by the optical floating zone technique and characterized by X-ray diffraction at room temperature. Atomic parameters were refined in space group R\overline 3m. The structure is isomorphous with that of other materials belonging to the YbFe2O4 family. Magnetic measurements suggest spin glass behavior with an ordering temperature around 20 K. The electrical resistivity of the material was measured. The site symmetry of all the atoms is 3m.
