Abstract

We use inelastic neutron scattering to establish the modulation vectors and correlation lengths for the incommensurate magnetic fluctuations in metallic samples of La2-xSrxCuO4 with x=0.075 and 0.14. In notation appropriate for a square lattice where the magnetic instability in the undoped case occurs at (,), the vectors are along (,0) and (0,).The correlation length is larger than the distance between carriers, is weakly dependent on x, and changes significantly between 12 and 100 K for both compositions.
