PREPARED La_xZn_xBa_((1-x))Fe_((12-x))O_(19) FERRITES BY OXALATES COPRECIPITATION METHOD

Du Youwei Lu Huaixian  
The magnetoplumbite structure La_x Zn_xBa_((1-x)) Fe_((12-x))O_(19) ferrites were prepared by chemical coprecipitating from mixed chlorides solution using ammonicum oxalate as a precipitant. The phase transition and magnetic properties have been studied during sintering procees. The main results are as follows: 1) Solid solution of the(La, Ba, Zn, Fe)C_2O_4°nH_2O based on FeC_2O_4° 2H_2O can be formed when the substituted quantily of La ions is less than 0.8. 2) The temperature forming La_xZn_xBa_((1-x))Fe_((12-x))O_(19) phase increases with the increasing 3) When the value of x in the La_xZn_xBa_((1-x))Fe_((12-x))O_(19) increases, the specific magnetization at room temperature increases and the Curie point decreases.
