Anisotropic pairing in heavy fermion superconductors - Its origin and effects on transport properties.
01 January 1987
An origin of the anisotropic Cooper pairing in heavy fermion superconductors is discussed on the basis of the interaction mediated by the antiferromagnetic spinfluctuations which are observed in experiments. Such interaction promotes the anisotropic even-parity pairings but suppresses the odd-parity as well as the isotropic even-parity pairings. Transport properties at low temperatures are also discussed in relation to the gap structure of Cooper pair, which shows that different kinds of existing experiments can be explained by a gap vanishing along the line(s) on the Fermi surface.
