Abstract

The nature of the superconducting state in quasi-one-dimensional organic conductors has remained controversial since its discovery. Here we present results of [Formula presented] NMR Knight shift ([Formula presented]) experiments in [Formula presented] under 7 kbar of pressure with a magnetic field aligned along the most conducting [Formula presented] axis. We find no noticeable shift in [Formula presented] upon cooling through the superconducting transition. Since [Formula presented] directly probes the spin susceptibility [Formula presented], the fact that [Formula presented] remains unchanged through the superconducting transition strongly suggests spin-triplet superconductivity.
