Abstract
We report a neutron scattering study of the spin fluctuations in samples of La1.89Sr0.11CuO4 which are ∼80% superconducting with Tc=10 K. The structure factor S(Q) reflects three-dimensional modulated spin correlations with an in-plane correlation length of order 18±6 Å. The fluctuations evolve with temperature from being predominantly dynamic at high temperatures to mainly quasielastic (|ΔE|<0.5 meV) at low temperatures. No significant differences are observed in the normal and superconducting states.
