Neutron scattering from magnetic excitations in Bi2Sr2CaCu2O(8+delta)

We report inelastic neutron scattering measurements of the copper oxide system Bi2Sr2CaCu2O(8+delta) in which we observe a magnetic resonance peak in the superconducting state. This result implies that this excitation phenomenon is a general feature of the copper oxide superconductors, so extending...

Zusammenfassung:	We report inelastic neutron scattering measurements of the copper oxide system Bi2Sr2CaCu2O(8+delta) in which we observe a magnetic resonance peak in the superconducting state. This result implies that this excitation phenomenon is a general feature of the copper oxide superconductors, so extending the empirical basis for its theoretical description. (Author)
