Effect of Y2O3 dopant on dielectric, magnetic, magnetodielectric properties of Bi0.95La0.05Fe0.95Ti0.05O3 ceramics

The Bi0.95-xLa0.05YxFe0.95Ti0.05O3 (BYFO) (x = 0, 0.04, 0.06, 0.08, 0.10) ceramics were synthesized by traditional solid phase method. The samples for BYFO ceramics were tested for X-ray diffraction (XRD) techniques, magnetic hysteresis (M–H)loops, scanning electron microscope (SEM). The leakage cur...

Description
Summary:The Bi0.95-xLa0.05YxFe0.95Ti0.05O3 (BYFO) (x = 0, 0.04, 0.06, 0.08, 0.10) ceramics were synthesized by traditional solid phase method. The samples for BYFO ceramics were tested for X-ray diffraction (XRD) techniques, magnetic hysteresis (M–H)loops, scanning electron microscope (SEM). The leakage current were weakened because highly dense microstructure and low porosity ceramics were compounded. When x = 0.06, remanent polarization (Pr) is 0.3079 μC/cm2, and saturization polarization (Ps) is 1.3542 μC/cm2 for BYFO ceramics. Saturation magnetization (Ms) and remanent magnetization (Mr) are increased to 1.91926 emu/g, 1.43179 emu/g respectively. The obtained values of the magnetodielectric coefficient (αMD) comes to maximum value, which is 15.64% for x = 0.08. •Bi0.95-xLa0.05YxFe0.95Ti0.05O3 (BYFO) ceramics were synthesized by solid phase method.•The dielectric and magnetic properties were improved.•The magneticdielectric effect become more evident because of doped Y3+.
