Abstract

C13 nuclear magnetic resonance measurements were performed on κ−(BEDT−TTF)2Cu(NCS)2, with the external field placed parallel to the quasi-2D conducting layers. The absorption spectrum is used to determine the electronic spin polarization Ms as a function of external field H at a temperature T=0.35 K. A discontinuity in the derivative dMs/dH at an applied field of Hs=213±3 kOe is taken as evidence for a Zeeman-driven transition within the superconducting state and stabilization of inhomogeneous superconductivity.
