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

The Bi_0.95-xLa_0.05Y_xFe_0.95Ti_0.05O₃ (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 (P_r) is 0.3079 μC/cm², and saturization polarization (P_s) is 1.3542 μC/cm² for BYFO ceramics. Saturation magnetization (M_s) and remanent magnetization (M_r) are increased to 1.91926 emu/g, 1.43179 emu/g respectively. The obtained values of the magnetodielectric coefficient (α_MD) comes to maximum value, which is 15.64% for x = 0.08.
