摘要：

The investigations of two-magnon Raman scattering were carried out with high spatial resolution in YBaCuO single crystals with different oxygen content. From the analysis of Raman data it was found that the increase of oxygen content results in a rapid increase of magnon damping and disappearance of two-magnon scattering band from RS spectra.
