"The aim of present work is to synthesis and study the structural properties of Al doped Ni-Cd ferrites, series by ceramic method. The samples are sintered at a temperature of 1100 C with sintering time of t=9, 11, 13, 15 hrs. The samples were characterized by X-ray diffraction, scanning electron microscope, energy dispersive X-ray analysis and Fourier transform-Infrared. The single phase simple cubic spinel structure is confirmed by X-ray diffraction patterns. The lattice parameter is found to be in the range of 8.478 Å - 8.481 Å. The uniform size distribution is observed in the scanning electron microscope micrographs. The elemental analysis is done by energy dispersive X-ray analysis confirming the presence of all the metal ions present in the ferrite formula. Fourier transform-Infrared spectra showed two bands υ1 (581-582 cm-1) and υ2 (less than 400 cm-1) which are attributed to metal oxygen bond vibrations at tetrahedral and octahedral sites respectively.
