摘要

The dynamic magnetic correlations have been characterized in a large, orthorhombic single crystal of YBa2Cu3O6+x with x=0.6, having a Tc of 53 K. Inelastic-neutron-scattering measurements reveal a gap (zero magnetic cross section) of 5 meV in the spin-excitation spectrum at 10 K. The size of the gap fits well between those reported by Rossat-Mignod et al. for x=0.51 and 0.69. However, the rapid change in the gap size with a relatively small change in Tc is not understood.
