Fecha de publicación: | 2013 | Editor: | American Chemical Society | Citación: | Chemistry of Materials 25(9): 1533-1541 (2013) | Resumen: | Ti-doped BiFeO3 ceramics prepared by a mixed-oxide route were structurally characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM), giving evidence of the formation of an inner structure at the nanometric scale. The observed nanograins are separated by Ti-rich areas that originate due to the tendency of the titanium dopant to segregate from the perovskite lattice. Such a peculiar nanostructure is responsible for the changes produced in both the electrical and the magnetic properties of BiFeO3 upon titanium doping: the Ti-rich interfaces act as resistive layers that increase the direct-current (dc) resistivity of the material, while the existence of structural domains in the scale of tens of nanometers causes a ferrimagnetic-like behavior with a huge coercive field (on the order of 20 kOe), even at room temperature. | URI: | http://hdl.handle.net/10261/94620 | DOI: | 10.1021/cm303743h | Identificadores: | doi: 10.1021/cm303743h e-issn: 1520-5002 issn: 0897-4756 |
