摘要: Abstract Pure and doped BaTiO3 (BTO) with different doping concentrations e.g. Ba0.97La0.03Ti1−xNixO3 (x = 0.03, 0.05, 0.07) were synthesized via sol–gel method. X-ray diffraction (XRD) patterns confirm the single phase formation for all samples. Polarization versus Electric field (P–E) loops pure BTO shows non linear ferroelectric loop which tends towards lossy capacitor behavior as Ni concentration increases from x = 0.03 to 0.07. Moreover, it is observed that value of dielectric constant loss found maximum x = 0.07 sample. Room temperature magnetization magnetic (M–H) indicate existence ferromagnetism in However, sample presence diamagnetic this Magnetoelectric study reveals magnetoelectric coupling only 0.05 quadratic coefficient (β) sample, 3.34 × 10−4 μV/cm Oe2.
