Abstract: Mn inclusion in the oxide based diluted magnetic semiconductor Zn_1−x Mn _x O (x = 0.04, 0.06, 0.08, and 0.10) grown by standard high temperature solid state reaction technique has been studied. The local and average structure of Zn_1−x Mn _x O was characterized by the super resolution technique maximum entropy method and pair distribution function analysis using the X-ray powder data. Magnetic studies on this material using a Vibrating Sample Magnetometer were also carried out to ascertain the doping level in Zn_1−x Mn _x O.
