摘要

Physics and Astronomy (miscellaneous)

We studied ultrafast dynamics and photoinduced mechanical strain of BiFeO ₃ thin films by dual-color transient reflectivity measurements (ΔR/R). Anisotropic photostriction in BiFeO ₃ is found to be mainly driven by the optical rectification effect. Results of the photostriction at various thicknesses show that the estimated sound velocity along [110] direction of BiFeO ₃ is 4.76 km/s. © 2012 American Institute of Physics.
