| Abstract: | Ni1-xZnxFe2O4(x = 0,0.1,0.2,0.3,0.4,0.5,0.7 and 1) ferrite powders were prepared by a molten salt method.The crystal structure and magnetic properties were investigated by means of XRD,IR,and SQUID.The results indicated that the saturation magnetization Ms of Ni1-xZnxFe2O4 ferrite reached its maximum of 79.3 emu.g-1 as x = 0.3.Subsequently,we investigated the magnetic interaction in the sample,and the related mechanism was discussed. |
