Enhanced magnetic and dielectric properties of BiFeO3-BaFe12O19 solid solution
Magnetic and dielectric properties of multiferroic (1-x)BiFeO 3 -xBaFe 12 O 19 (x=0.03, 0.05, 0.07, 0.09 wt%) solid solution synthesized by state solid were investigated. Morphology of the sample is determined by SEM, indicating that the grain has been shrink, and all samples have been irregular. With increasing of BaFe 12 O 19 , saturation magnetization increased from 0.07 to 0.7 eμg, and coercivity increased from 160 to 3150 Oe. Through solid solution BaFe 12 O 19 , we greatly improved the coercivity. With BaFe 12 O 19 increasing, dielectric constant increases monotonously, while dielectric lose kept a low value. The increase in coercivity of the sample allows the solid solution to be used as a candidate for advanced packaging materials and sensors.
