Deformation of a bismuth ferrite nanocrystal imaged by coherent X-ray diffraction
Deformation of a bismuth ferrite nanocrystal imaged by coherent X-ray diffraction
Abstract. Perovskite materials that contain transition metal-oxides often exhibit multifunctional properties with considerable utility in a device setting. BiFeO3 is a multiferroic perovskite material that exhibits room temperature anti-ferromagnetic and ferroelectric ordering. Optical excitation of BiFeO3 crystals results in an elastic structural deformation of the lattice with a fast response on the pico-second time scale. Here we report on dynamic optical excitation coupled with Bragg coherent X-ray diffraction measurements to investigate the structural properties of BiFeO3 nanoscale crystals. A continuous distortion of the diffraction speckle pattern was ob- served with increasing illumination. This was attributed to strain resulting from photo-induced lattice deformation.
