Abstract

Neutron scattering measurements were carried out to study the static magnetic structures of superconducting La_2-xSr_xCuO₄ with x = 0.10 and 0.13. We found that there exist incommensurate magnetic peaks around (π, π) which start appearing below T^*. Combined with previous reports for x = 0.10, 0.12 and 0.15, we noticed that T^* becomes maximum at x = 0.12. The static magnetic correlation length ξ was estimated to be 88 angstrom for x = 0.13, which is considerably shorter than ξ > 200 angstrom reported for x = 0.12.
