"Multiferroic properties of modified BiFeO3-PbTiO3-based ceramics: Random-field induced release of latent magnetization and polarization," PHYSICAL REVIEW B 72(10): 104434. DOI: 10.1103/PhysRevB.72.1044341098-0121http://hdl.handle.net/10919/25395It has been found that aliovalent-substituted BiFeO3-PbTiO3-based polycrystalline materials have significantly enhanced multiferroic properties. Relative to unmodified BiFeO3, our results for modified BiFeO3-PbTiO3-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.application/pdfen-USIn CopyrightMorphotropic phase boundaryHigh temperatureBismuth ferriteBifeo3TransitionsAntiferromagnetsCrystalsRelaxersPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevB.72.104434https://doi.org/10.1103/PhysRevB.72.104434
