Evidence from ${}^{77}$Se Knight shifts for triplet superconductivity in (TMTSF)${}_2$PF${}_6$

I. J. Lee, D. S. Chow, W. G. Clark +4

The layered quasi-one-dimensional molecular superconductor (TMTSF)${}_2$PF${}_6$ is a very exotic material with a superconducting order parameter whose ground state symmetry has remain…
