Abstract

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.
