We performed magnetic inelastic neutron-scattering experiments on La1.93Sr0.07CuO4 over a wide range of omega and T, 2 less than or equal to 44MeV and 1.5 less than or equal to T (- 300 K. the dynamic susceptibility "chi" (q,omega) of this underdoped high-T-c superconductor (T-c=17K) is characterized by broad, incommensurate peaks. Here, the incommensurate wavevector delta (omega) is approximately 0.07 reciprocal lattice units at low T and omega.
