Room-temperature ferromagnetic behavior of undoped cadmium sulphide (CdS) and Ni-doped CdS thinfilms prepared by chemical bath deposition technique is reported. The crystallite sizes of the thinfilms have been characterized by X-ray diffraction pattern. The particle sizes increase from 11 to 40 nm with the increase of Ni content in the CdS thinfilms. scanning electron microscope results indicated that CdS thinfilms is made up of aggregate of spherical-like particles. The composition was estimated by Energy dispersive analysis of X-ray and reported. Spectroscopic studies revealed considerable improvement in transmission and the band gap of the films decreased from 2.62 to 2.28 eV with addition of Ni dopant that is associated with variation in crystallite sizes in the nano regime. Magnetization measurements indicate that the Ni doped CdS thinfilms exhibited ferromagnetism and the saturation magnetization decreases with the increase of crystal sizes in the Ni doped CdS nano thinfilms. This finding in CdS thinfilms should be focus of the future electronic and spintronics devices.
