Electronic structures and NMR T-1(-1) in quasi-one-dimensional organic superconductor (TMTSF)(2)PF6

摘要

On the basis of the Bogoliubov de Gennes theory, electronic structures around a vortex in quasi-one-dimensional organic superconductor (TMTSF)(2)PF6 are studied at the quarter-filling electron density in magnetic fields applied parallel to the conduction chain. We consider three pairing symmetries (d-, p- and f-wave) in superconductors. In d- and f-wave symmetries, nuclear relaxation rate T-1(-1) is proportional to temperatures because quasiparticles around the vortex relax spins. (c) 2006 Elsevier B.V. All rights reserved.
