摘要: Antiferromagnetic spin fluctuations in superconducting YBa{sub 2}Cu{sub 3}O{sub 6+{ital x}} have been studied using inelastic neutron scattering. In a crystal with {ital x}=0.5 and T}{sub c}}=50 K, we observed at 12 K having cross section which increases increasing excitation energy. The data are consistent highly overdamped waves very short spin-spin correlation length.
