NEURON SCATTERING STUDIES OF THE MAGNETIC FLUCTUATIONS IN YBa2Cu3O7−δ
/ Abstract
Neutron scattering measurements were made on the spin fluctuations in YBa2Cu3O7-delta for different oxygen doping levels. Incommensurability is clearly observed for oxygen concentrations of 6.6 and 6.7 and is suggested for the 6.93. Measurements of the resonance for the O-6.6 concentration show that it exists in a broadened and less intense form at temperatures much higher than T-c. (C) 1998 Elsevier Science Ltd.
