We present Raman data on both single-crystal and thin-film samples of the multiferroic PbFe 0.5 Nb 0.5 O 3 . we show first that the number and selection rules of Raman lines is compatible with a face-centered cubic Fm-3m structure, as is known in other ABO 3 relaxors, such as The increase in frequency with increasing temperature for the lowest-energy F 2g phonon mode is particularly unexpected. These changes suggest the transition of crystal structure from an ordered phase to a disordered one near T B . The Raman study revealed phonon anomalies in the vicinity of T m and T N that are attributed to the dynamical behavior of polar nano-regions (PNRs) and spin-phonon coupling due to its relaxor and multiferroic nature respectively, which is well supported by dielectric and magnetic properties of the PFN thin film. Softening of the Fe-O mode was observed near the T N . We correlate the anomalous shift of the Fe-O mode frequency with the normalized square of the magnetization sublattice; agreement with the experimental 2 results suggest strong spin-phonon coupling near T N due to phonon modulation of the superexchange integral, however the shifts in frequency with temperature are small (< 3 cm -1 ).

“…Lead iron tantalate (Pb(Fe 0.5 Ta 0.5 )O 3 ) is another type of magnetoelectric material where ferroelectrically active Ta 5+ cations are partially substituted by magnetic Fe 3+ ions of a different valence state, the so-called paramagnetic substitution [5]. As a consequence, Pb(Fe 0.5 Ta 0.5 )O 3 exhibits antiferromagnetic ordering at temperatures below 130-180 K as well as ferroelectric ordering at temperature below 270 K [8][9][10][11][12].…”

IntroductionMaterials that exhibit ferromagnetic and ferroelectric ordering in the same phase are named magnetoelectrics, which are part of a larger group of multiferroics. Multiferroics possess at least two ferroic orderings at the same time. Magnetoelectric materials are characterized by a strong coupling between the magnetic and electric subsystems, which means that the magnetic fi eld is able to induce electric polarization and vice versa.The fi rst single-phase multiferroic perovskite oxides (ABO 3 ) were discovered in early 1960s. However, very limited progress has been made during the past several decades [1][2][3][4][5][6]. The signifi cant development of multiferroic materials started with the successful synthesis of multiferroic thin fi lms [7].Magnetoelectrics are widely used as transducers, actuators, detectors, and other sensors that are characterized by high dielectric permittivity and magnetic permeability [1][2][3][4][5][6][7] Abstract. Multiferroic 0.5BiFeO 3 -0.5Pb(Fe 0.5 Ta 0.5 )O 3 solid solution is a material that exhibits ferroelectric and antiferromagnetic orderings in ambient temperature. The solid solution was obtained as a result of a conventional reaction in a solid state. The obtained material is a dense, fi ne-grained sinter whose surface was observed by scanning electron microscopy (SEM) and stoichiometry was confi rmed by energy dispersive X-ray spectroscopic (EDS) analysis. According to the X-ray powder diffraction (XRD) measurements, the main phase is R3c space group with admixture of Pm-3m regular phase. Small contribution of pyrochlore-like phase was also observed. Mössbauer spectroscopy suggested random distribution of Fe 3+ /Ta 5+ cations in the B sites of ABO 3 compound. Reduction of the magnetic hyperfi ne fi eld with an increase in the substitution of Ta 5+ in Fe 3+ neighbourhood was also observed.
