N2 - Elastic magnetic peaks around (π, π) have been studied in La2-xSrxCuO4 (LSCO) by neutron scattering. Recently in superconducting LSCO of x = 0.12, we found that the incommensurate elastic peak (IC peak) appears around 31 K which is very close to Tc. The line width reaches almost resolution limit, which indicates that the static magnetic correlation length exceeds 200 angstrom-1 isotropically in the CuO2 planes. Furthermore recently in the course of studying the IC peak, we found the new experimental condition where the signals can be observed more clearly. The signal-to-noise ratio (S/N) is much more improved (approx. 1.4) than that at the previous experiment (approx. 0.6).
