Abstract

We present de Haas-van Alphen (dHvA) measurements of the nonmagnetic borocarbide LuNi2B2C. In the superconducting state below the upper critical field, B-c2, the dHvA signal shows an additional damping. For some field orientations we observe a very strong damping close to B-c2 and only a very weak effect at lower fields in the superconducting state. We discuss the origin of the different dampings and their relation to the superconducting gap. (c) 2007 Elsevier B.V. All rights reserved.
