Abstract

From the thermal transport measurements in rotating magnetic fields H, we pinned down the superconducting gap structure of CeIrIn5. Clear fourfold oscillation was observed when H is rotated within the ab-plane, while no discernible oscillation was observed within the bc-plane. In sharp contrast to previous reports, our results are most consistent with dx2-y2 symmetry, implying that the superconductivity of CeIrIn5 is mediated by antiferromagnetic spin fluctuations as well as that of CeRhIn5 and CeCoIn5. © 2009 IOP Publishing Ltd.
