La 1.84Sr 0.16CuO 4 single crystalSTMScanning tunneling microscopy and spectroscopy (STM/STS) measurements have been performed on the nearly optimally doped La 1.84Sr 0.16CuO 4 (LSCO) single crystal with T c=39 K. The surface topography has been observed for the first time and revealed the ...
Micro-probed raman scattering in La2-xSrxCuO4LaSrCuOtwo-magnonmicro analysisThe two-magnon scattering peak in La2-xSrxCuO4 single crystals has been investigated by using a micro-probed Raman scattering technique. The peak intensity and the shape of two-magnon scattering are very sensitive to ...
This absorption, the intensity of which increases with Sr doping, implies Sr doping induces electronic states within the gap of La2CuO4. With further Sr doping, the density of states forms a band about 1 eV wide and centered at about 0.5 eV above the top of the original valence band. ...

Methods Single crystals of La2−xSrxCuO4 (LSCO) were grown using a travelling-solvent-floating-zone technique. The actual doping x(= p) of each crystal was estimated from its Tc using the empirical relation Tc0 = Tcopt(1 − 82.6(p − 0.16)2) (ref. 31). The in-plane ...
