Study of Electrical Transport Properties of Cadmium-Doped Zn–Mn Soft Ferrites by Co-precipitation Method

Cadmium ion doped in Zn–Mn soft ferrites was synthesized by co-precipitation method. Cadmium content can improve the micro-structure, magnetic, electrical, optical, and vibrational properties. Single-phase cubic structure of all samples of cadmium-doped Zn–Mn soft ferrites was confirmed by using X-ray diffraction technique. Crystalline size of the material was investigated by using XRD pattern. FTIR analysis observed that the metal oxide group (M–O) exists in the presented samples. The DC resistivity decreased as the concentration of cadmium and temperature increases, and also, with the increase in cadmium contents, optical band gap decreased and Raman shift increased.
