AbstractCeramic solid solution described by formula Bi0.5Nd0.5FeO3 was prepared by standard solid-state sintering method. X-ray diffraction proved the formation of a single-phase sample with orthorhombic structure typical of NdFeO3. Vibrating sample magnetometry revealed weak ferromagnetic behavior of the ceramics up to the Curie temperature Tc = 642 K. Local atomic configurations and local magnetic fields were investigated by 57Fe Mössbauer spectroscopy. It was shown that substitution of a single Nd3+ ion by Bi3+ ion in the orthorhombic NdFeO3 lattice causes a decrease of hyperfine magnetic field experienced by 57Fe ion by the value of 0.186 T. Measurements of the magnetoelectric effect showed that the maximal registered value of the magnetoelectric voltage coefficient was equal to 0.46 mV/(cm·Oe). © 2019 Elsevier Ltd and Techna Group S.r.l.
