Abstract

Elastic magnetic peaks around (π, π) have been studied in La_2-xSr_xCuO₄ (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 T_c. 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).
