Abstract
The study to explore the effects of Mn doping on structural, morphological, and magnetic properties of CdTe nanostructures prepared by co-precipitation route is reported. The size of nanoparticles measured using X-ray diffraction increased after doping but then remains constant upon increase in concentration of the dopant atoms. The analysis of surface morphology carried out using scanning electron microscopy indicates the improvement in homogeneity and sharpness in shape of the needle-like architectures. The measurements of magnetization as a function of applied field using a vibrating sample magnetometer revealed a magnetic hysteresis behavior for all doped samples. The value of saturation magnetization was observed to consistently decrease with increase in doping concentration which reveals the presence of antiferromagnetic ordering of Mn 2+-Mn 2+ nature in the materials.
