Abstract
The polarization state of a thin Pb(ZrTi)O-3 film is probed by optical seco nd-harmonic generation (SHG) while applying an external voltage (a sine wav e). A hysteresis in the SHG intensity is observed that corresponds to the d ielectric hysteresis and is analyzed using a phenomenological relation betw een the SHG intensity and the dielectric polarization. Based on this model, the polarization state of the film during polarization reversal is mapped. (C) 2001 American Institute of Physics.
