Structural, vibrational and magnetic studies of Pb(Fe0.585Nb0.25W0.165)O3 multiferroic solid solution

In this paper, the complex structured A(B′B′′B′′′)O3 perovskite Pb(Fe0.585Nb0.25W0.165)O3(PFNW) type multiferroic, was successfully synthesized in a single phase by a single step solid state reaction method and optimized synthesis parameters are calcination at 700 °C/2hr and sintering at 800 °C/3hr. The detailed room temperature (RT) structural, vibrational and temperature dependent magnetization were carried out through the X ray diffraction, Raman spectroscopy and vibrating sample magnetometer (VSM). Rietveld refinement was carried out on RT XRD data it confirms the cubic structure with Pm-3m space group, the obtained lattice parameters: a = b = c = 3.9948 A, and α = β = γ = 90°. The RT Raman spectroscopy confirms the formation of cubic structure broad peak at 820 cm−1, related to the A1g mode. PFNW exhibits a cusp at around 255 K in the temperature dependent magnetic susceptibility corresponding to the Neel temperature (TN) and another peak around 10 K (Tsg) corresponding to spin-glass like transition....
