Abstract

Structural, optical and room-temperature (RT) ferromagnetic properties have been obtained in the formula (1-x)BaTiO₃-xBaNi_0.5Nb_0.5O_3-δ ((1-x)BT-xBNN) ceramics. All the ceramics have single perovskite structure without any impurity phase, but show doping-induced structural transition from tetragonal to rhombohedral phase. The possible mechanism is used to analyze the change of lattice structure. Raman spectroscopy analysis not only further confirms the presence of phase transition, but also indicates the difference in lattice vibrational modes for each sample. Moreover, the incorporation of BNN into BT system leads to the modified magnetism. Especially, the standard S-type curves are observed in x = 0.03 and x = 0.05 compositions, which can be explained by the F center exchange theory. These physical properties are helpful to further study the applications in multifunctional apparatus.
