Abstract

Polarized and unpolarized neutron scattering have been used to determine the effect of superconductivity on the magnetic excitation spectra of YBa₂Cu₃O_6.5 (T_c = 52K) and YBa₂Cu₃O_6.7 (T_c = 67K). Pronounced enhancements of the spectral weight centered around 25 and 33 meV, respectively, are observed below T_c in both crystals, compensated predominantly by a loss of spectral weight at higher energies. The data provide important clues to the origin of the 40 meV magnetic resonance peak in YBa₂Cu₃O₇.
