Abstract

Non-magnetic La and Y impurities in CeCu 2.2 Si 2 give rise to a “diamagnetic” pair-breaking effect and, in addition, Gd causes “paramagnetic” pair breaking. In dilute (0 1-x La x Cu 2.2 Si 2 alloys an “alloying-induced depression of incoherent scattering” is observed and related to the formation of antiferromagnetic order at several K.
