In this study we have synthesized lead-free polycrystalline sample of (La1/2Li1/2)(Fe1/2V1/2)O3 multiferroic by a standard high-temperature solid-state reaction technique. TGA has been carried out to observe the weight loss of the material with rise in temperature. The formation of the material has been confirmed by preliminary structural analysis using X-ray diffraction data. The dielectric permittivity (constant), loss tangent, impedance, and electric modulus of silver coated pellet sample were measured in a wide frequency range (1 kHz–1 MHz) at different temperatures (30–375 °C). The Nyquist plots show the contributions of grain and grain boundary effect in the impedance characteristics of the material. The bulk resistance calculated from the impedance data decreases with increase in temperature showing negative temperature coefficient of resistance (NTCR)-type behaviour of the material. The frequency dependence of ac conductivity at different temperature indicates that the material obeys Jonscher’s universal power law. The nature of variation of dc conductivity follows Arrhenius law. Detailed studies of modulus spectrum suggest that the material exhibits non-Debye type of relaxation mechanism, which is consistent with the impedance data. The room temperature magnetic (M-H) and ferroelectric (P-E) loops confirm the ferromagnetic and ferroelectric ordering present in the prepared material.
