The individual k\parallel and k\perp stripe excitations in fluctuating spin-charge stripes have not been observed yet. In Raman scattering if we set, for example, incident and scattered light polarizations to two possible stripe directions, we can ob

The mechanism of the high temperature hole-doped superconductivity was investigated by Raman scattering. The Raman selection rule is unique, so that anisotropic magnetic excitations in a fluctuating spin-charge stripe can be detected as if it is stat

Two magnon excitations and the nodal spin density wave (SDW) gap were observed in BaFe2As2 by Raman scattering. Below the SDW transition temperature (TSDW) nodal SDW gap opens together with new excitations in reconstructed electronic states. The two-

Raman spectra of La$_{2-x}$Sr$_x$CuO$_4$ are similar to those of Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ except for the split two-magnon peaks at the stripe phase and the stronger step-like decrease in the low energy $B_{\rm 2g}$ spectra. The suppressed $

The dynamical stripe structure relating to the "1/8 problem" was investigated in La$_{2-x}$Sr$_x$CuO$_4$ utilizing the high frequency response of Raman scattering. The split of the two-magnon peak due to the formation of the stripe structure was obse

The Raman spectra on the cleaved surface of La$_{2-x}$Sr$_x$CuO$_4$ is found to be different from those on the mechanically polished or chemically etched surface. On the cleaved surface, the step-like increase of the scattering intensity below 700 cm
