Investigation of electric, dielectric, and magnetic properties of Li+1 and Mo+6 co-doped BiFeO3

The bulk ceramics bearing chemical formula BiFeO3 and (BiLi)(1/2) (Fe2/3Mo1/3)O-3 (abbreviated as BFO and BLFMO respectively) are synthesized using mixed oxide route. The physical properties (structural, dielectric, electric and magnetic) are tailored in Li and Mo co-doped BiFeO3. The phase evolution suggests that there is transformation from rhombohedral (pure BFO) to orthorhombic (BLFMO). Micro-structural suggests that due to co-doping the size of the grain is smaller than BFO. The dielectric properties of both BFO and BLFMO measure with an LCR meter varying the frequency (10(2)-10(6)Hz) and temperature (30-375 degrees C). The leakage current decreases in BLFMO. The magnetic hysteresis loop owing weak ferromagnetism is depicted for Li and Mo co-doped BFO. The fabricated material will be base for various applications like filter and buffering.
