Abstract
The upper critical field H-c2 of kappa-(ET)(2)Cu[N(CN)(2)]Br under magnetic fields parallel to the superconducting layer has been determined based on the temperature dependence of the out-of-plane resistance. The H-c2 exceeds the Pauli paramagnetic limit value based upon a weak coupling BCS model an d tends to increase further toward lower temperatures. (C) 2001 Elsevier Sc ience B.V. All rights reserved.
