Título da revista, periódico, livro ou evento: | Crystals | Volume: | 13 | Número: | 6 | Resumo: | BiFeO3 fibers were prepared by the Laser Floating Zone (LFZ) technique using different growth speeds. The structural characterization of the samples was undertaken using X-ray diffraction (XRD) and Raman spectroscopy, the morphological characterization by scanning electron microscopy (SEM), and the electrical characterization by impedance spectroscopy. The XRD patterns showed that BiFeO3 was the major phase in all the samples. Fibers grown at 10 mm/h showed more promising structural and morphological properties. The dielectric characterization revealed that all samples have at least one dielectric relaxation phenomenon that is thermally activated. It was also verified that the dielectric constant is higher at a growth pull rate speed of 10 mm/h. | URI: | https://hdl.handle.net/10316/113187 | ISSN: | 2073-4352 | DOI: | 10.3390/cryst13060960 | Direitos: | openAccess |
