μSR studies of the flux vortex phases in a BEDT-TTF superconductor

| الملخص: | μSR has been used to probe the structure and stability of the flux vortex array in the organic superconductor κ-(BEDT-TTF)2Cu(SCN)2. At temperatures below 5 K and fields below 5 mT the internal field distribution is found to closely match that expected for a three dimensional (3D) Abrikosov flux line lattice (FLL). Careful studies in this 3D-FLL regime have enabled an improved measurement of the temperature dependence of the superconducting penetration depth to be made. A linear term is found in the temperature dependence of the penetration depth, suggesting the presence of line nodes in the gap parameter and d-wave pairing. |
