Abstract

It has been found that aliovalent-substituted $Bi Fe O_{3} − Pb Ti O_{3}$ -based polycrystalline materials have significantly enhanced multiferroic properties. Relative to unmodified $Bi Fe O_{3}$ , our results for modified $Bi Fe O_{3} − Pb Ti O_{3}$ -based ceramics reveal: (i) a dramatic increase in the electric-field-induced polarization; and (ii) the establishment of a remanent magnetization. The results evidence the destruction of a space-modulated spin structure in bulk materials, via substituent effects, releasing a latent magnetization locked within the cycloid.
