Structural, Optical, Electrical and Magnetic Properties of Ti0.9Co0.1O2, Ti0.9Cr0.1O2, Ti0.9Cr0.04Co0.06O2

Three samples of dilute magnetic semiconductors (DMS) have been prepared by solid state reaction method at sintering temperature of 950 °C for 5 hours. Their structural, optical, electrical and magnetic properties are optimized by X-Ray Difractometer (XRD), UV-Visible spectrophotometer (UV-Vis), Four point probe method and Vibrating sample magnetometer (VSM) measurements respectively. Surface morphology has been studied by using scanning electron microscope (SEM). Structural analysis showed that a single phase Rutile structure has been attained while Optical and resistivity measurements confirmed their semiconducting behaviors. Magnetic measurements showed weak Ferromagnetic and Paramagnetic behaviors at room temperature.
