| Abstract: | Nano - crystalline spinel ferrite Zn0.25Mg0.25Ca0.5Fe2O4 (x = 0 - 0. 25) doped with Ca2+ was prepared with citrate precursor by sol - gel process. And the magnetic property and crystal structure were characterized. The result shows that the magnetization and coercivity of the ferrite are influenced by the addition of Ca2 + . |
