| Abstract: | The spinel structure Zn1.8Co0.2TiO4 single crystals with 5 mm diameter and 30 mm length were successfully grown by an optical floating zone method. The as-grown crystals were characterized by X-ray diffraction (XRD), Raman and X-ray photoelectron spectroscopy (XPS). Some Zn2+ ions at tetrahedral and octahedral sites should be replaced by doped transition metal Co2+ ions. The temperature-dependent Raman spectra of spinel Zn1.8Co0.2TiO4 crystals were also described. The optical phonon behaviors of Zn1.8Co0.2TiO4 are stable within the temperature range. The magnetic properties of Zn1.8Co0.2TiO4 were investigated by using Physical Property Measurement System.The spinel structure Zn1.8Co0.2TiO4 single crystals with 5 mm diameter and 30 mm length were successfully grown by an optical floating zone method. |
