Investigation of the photostriction effect in BiFeO3 by means of infrared and optical spectroscopy — •Florian Burkert and Christine Kuntscher — Experimentalphysik II, Universität Augsburg, D-86159 Augsburg, Germany

It has been reported that BiFeO3 crystals change their size during illumination with visible light or ultraviolet radiation [1,2]. We studied the impact of this photostrictive effect on the optical properties of a BiFeO3 single crystal in the infrared up to the ultraviolet frequency range by using an FTIR spectrometer and a CCD spectrograph. During illumination with various radiation sources we observe the appearance of additional absorption features in the optical spectra. We will discuss possible origins of these new features.
