D-wave pairing symmetry in cuprate superconductors
Abstract
Phase-sensitive tests of pairing symmetry have provided strong evidence for predominantly d-wave pairing symmetry in both the hole- and electron-doped high-Tc cuprate superconductors. Temperature dependent measurements in YBa2Cu3O7-δ (YBCO) indicate that the d-wave pairing dominates, with little if any imaginary component, at all temperatures from 0.5K through Tc. In this article we review some of this evidence and discuss the implications of the universal d-wave pairing symmetry in the cuprates. © 2000 Elsevier Science B.V All rights reserved.
