| In the present work, three samples were investigated as candidates for room-temperature magnetoelectric materials: pure PFN, PFN–ferrite, and Mn-doped PFN–ferrite composite. The PFN compound consists of lead, iron, and niobium oxides, and its chemical formula is Pb(Fe0.5Nb0.5)O3. To improve its magnetic properties, pure PFN was combined with a nickel-zinc ferrite. Mn doping was used to suppress the formation of secondary phases during the synthesis process. The samples were prepared by free sintering and examined using X-ray diffraction, Mössbauer spectroscopy, and the lock-in technique. The obtained Mössbauer spectra indicate that the samples are paramagnetic. However, some evidence suggests the presence of an unresolved sextet at the base of the spectrum of the Mn-doped PFN–ferrite composite. The two-doublet model used in the fitting process indicates that Fe3+ ions occupy two distinct local environments. Lock-in measurements confirmed magnetoelectric coupling in the composite samples |
