- Abstract
- This work studies the sigma(s) and T-C of Co-Zn mixed Y-type ferrite (BaCo1-xZnxFe6O11, x = 0-1) powders, prepared by the co-precipitation method. The sigma(s, 0 kappa) and T-C change linearly with zinc content. CoY shows the highest T-C (595 K) and the lowest sigma(s, 0 kappa) (32.1 emu/g), while ZnY has the lowest T-C (373 K) and the highest sigma(s, 0 kappa) (73.6 emu/g). At room temperature, however, the maximum sigma(s) appears at around x = 0.75 (34.9 emu/g). The presence of zinc weakens the superexchange interaction, without changing the spin directions of other cations, over the whole composition range. It simply increases the net magnetic moment.
