文摘The Z ferrite Ba_ 3-xCo_2La_xFe_ 24O_ 41 doped lanthanum, obtained from a sol-gel precursor, was reported and confirmed that the chemical formula accord to the theoretic form by chemical analysis. The thermoanalysis results show that, as the amount of La 3+ increase, the producing temperature rises along with oxygen loss. The magnetic data reveal that doping influence the magnetism properties, which the magnetization and coercivity decrease as doping increases.
