摘要
Magnetoresistance measurements have been performed on CeNiSn at low temperatures down to 35 mK and in magnetic fields up to 20 T. Shubnikov-de Haas oscillations, observed for the first time, provide clear evidence that CeNiSn, formerly called a Kondo semiconductor, is a metal. The frequency and associated effective mass are 65 T and 13m(e) for the field direction parallel to the crystallographic c-axis. (C) 2002 Elsevier Science B.V. All rights reserved.
