摘要：

Inelastic neutron scattering performed at a spallation source is used to make absolute measurements of the dynamic susceptibility of insulating La2CuO4 and superconducting La1.86Sr0.14CuO4 over the energy range 15 less than or equal to (h) over bar omega less than or equal to 350 meV. The effect of Sr doping on the magnetic excitations is to cause a large broadening in the wave vector and a substantial change in the spectrum of the local spin fluctuations. Comparison of the two compositions reveals a new energy scale (h) over bar Gamma = 22 +/- 5 meV in La1.86Sr0.14CuO4.
