Abstract

Synthesis and characterization of Ba_1-xLaxFe₁₂O₁₉ based permanent magnet samples with variations in composition (x = 0; 0.02; 0.04; and 0.08) has been done. The method used is a solid state reaction. The phase formation of the sample Ba_1-xLaxFe₁₂O₁₉ was carried out at 1200^oC for 2 hours. The results of the X-ray diffraction pattern analysis show that all sample compositions have a single phase BaFe₁₂O₁₉. The results of magnetic properties testing using VSM showed that the best coercivity field and remanent magnetization values were obtained at the composition of x = 0.04. The effect of substitution of lanthanum into the barium atom can increase the number of magnetic domains which are indicated by the increase in the coercivity value of the material along with the increasing composition of x. It was concluded that the composition of Ba_1-xLaxFe₁₂O₁₉is a permanent magnet with the best product energy.
