"Incommensurate Magnetic Fluctuations in YBa₂Cu₃O₆.₆" by Pengcheng Dai, Herbert A. Mook et al.
 

Abstract

We use inelastic neutron scattering to demonstrate that the low-frequency magnetic fluctuations in YBa2Cu3O6.6 (Tc = 62.7 K) change from commensurate to incommensurate on cooling with the incommensurability first appearing at temperatures above Tc. For the energies studied, the susceptibility at incommensurate positions increases on cooling below Tc, accompanied by a suppression of the spin fluctuations at the commensurate points. These results suggest that incommensurate spin fluctuations may be a common feature for all cuprate superconductors.
