Co-doped ZnO (Zn1−xCoxO, x = 0.02 and 0.08) films were prepared by EB-PVD method. Structural analyses detects a lower density of VO for sample with x = 0.08. Optical results show the existence of a defect sub-band close to conduction band. Magnetic data reveal a huge MS for the film with x = 0.08, not correlated to VO. Magnetic properties are analyzed in the scope of BMP theory related to Zni defects.
