TL;DR: In this paper, the presence of Fe2+, detrimental to the ferroelectric and magnetic performance, was evaluated by x-ray photoelectron spectroscopy, showing no structural differences, uniformly distributed grains, a ferro-paraelectric transition temperature at 110°C and a normal diffuse phase transition (nonrelaxor behavior).

TL;DR: In this article, the dielectric behavior of ferroelectromagnetic Pb(Fe1∕2Nb1 ∕2)O3 ceramics obtained using the traditional ceramic method employing three different precursors was investigated by impedance spectroscopy in the temperature range of 200-300°C.

TL;DR: In this article, a microstructural and equivalent circuit model for the phase transition of ferroelectromagnetic Pb(Fe1 ∕2Nb1∕2)O3 ceramics obtained by different precursors is presented, and the frequency-temperature response was obtained from room temperature to 300°C and from 20Hzto 1Mz.

TL;DR: In this paper, a combination of the small signal response using the impedance spectroscopy technique and the electromechanical resonance method with the large signal response through standard ferroelectric hysteresis measurement, has been used with and without an applied magnetic field.

TL;DR: In this paper, a comparative analysis of Pmax, Pr, and EC parameters obtained from the full and remanent hysteresis loops is presented and correlated with a previous structural, morphological, and small signal dielectric frequency-temperature response study using the impedance spectroscopy technique.
