Magnetic Tests to Reveal Triplet Superconductivity in (TMTSF)2PF6 and a Possible Breaking of a Time Reversal Symmetry in Sr2RuO4, LBCO, and YBCO
Abstract
We propose methods to reveal the existence of a two-component triplet order parameter (which is recently suggested to break a time reversal symmetry in Sr2RuO4) and to test a possible two-component singlet d-wave order parameter in high-Tc superconductors (which may also break the time reversal symmetry). We have also determined a spin part (i.e., d(k) = [dx(k) ≠ 0, dy(k) = 0, dz(k) = 0)] of a triplet order parameter1,2 in (TMTSF)2PF6 under pressure by means of an analysis of the experimental Hc2 measurements (I. J. Lee et al., Phys. Rev. Lett. 78, 3555 (1997)).
