摘要：

The magnetic neutron scattering cross section in a crystal YBa2Cu3O6.5 (T(c) = 50 K) has been measured for energies between 4.5 meV and 15 meV and temperatures between 10 K and 275 K. From these data we extract the generalized susceptibility integrated around the (pi, pi) position [GRAPHICS] with those at 8.3 and 33.1 meV from a previous study. It is found that I(omega, T) exhibits the simple temperature scaling form found previously in La2-xSrxCuO4. Specifically, in YBa2Cu3O6.5, I(omega, T) = I(omega, 0) 2/pi tan-1 (omega/0.9 T). Implications of this behavior for the d.c. and infrared conductivity are discussed.
