Electrical and magnetic properties of (Ba₅LaTi₃V₇O₃₀)_1-x (BiFeO₃)x solid solution for different values of x

The solid solution (Ba₅LaTi₃V₇O₃₀)_1-x (BiFeO₃)x with x ranging from 0 to 0.5 were synthesized by high temperature solid-state reaction. X-ray diffraction (XRD) measurements show separate reflection peaks corresponding to both Ba₅LaTi₃V₇O₃₀ (BLTV) and BiFeO₃ (BFO) which confirms the formation of solid solution instead of any new compound. The electrical properties (i.e., dielectric constant, loss tangent and ac conductivity) were studied by using complex impedance spectroscopy in a wide range of temperature (RT-773K). It is observed that T_c increases significantly upto x=0.3 followed by decrease in Tc at x=0.4 and again it increases for x=0.5. Magnetization study was done through VSM which shows the presence of ferromagnetic property for x>0.3 so, predominately behaving as multiferroics in this range.
