Abstract

Five samples of Si doped Co â€“ Zn ferrite with general formula Co0.7+x Zn0.3 Six Fe2-2x O4 (x = 0.0 to 0.4) were prepared by double sintering ceramic technique. The physical and magnetic properties of these samples were studied by X-ray diffraction, high field hysteresis loop technique and a.c. susceptibility measurements. Lattice constant â€˜aâ€™ is found to decrease with increase in Si content from x=0.1 to 0.4. X-ray density dx decreases with increase in Si content. The particle size of the samples is found to vary in the range of 70 nm to 78.8 nm. Magnetic moment nB is found to increase with increase in Si concentration upto x < 0.2 and then it decreases for x > 0.3. A.C. susceptibility increases slowly with increase in temperature then decreases sharply and finally becomes zero near the curie temperature Tc.
