摘要：

Raman scattering spectra of ferroelectric single crystals has been observed with high spatial resolution using a near-field optical microscope. A Si cantilever with aperture of about 150 nm in diameter was used both as an illumination nano-source and a nano-detector of scattering light. The near-field Raman spectrum obtained by the subtraction of the background is in agreement with that of the micro-Raman scattering. Near the lattice defect in GMO, the sample was scanned in nano-scale and near-field Raman spectra were observed as a function of position on the surface.
