Point contact studies of the superconducting gap of CeRu₂
The measured dV/dI(V) curves of point contacts between the intermetallic compound CeRu2 in the superconducting state and the normal metal Cu correspond fairly well to the Blonder-Tinkham -Klapwijk model. It is used to obtain temperature and magnetic field dependence of the superconducting gap D. The...
