Scaling behavior of point contacts between a tungsten tip and the heavy-fermion superconductors

We investigated metallic point contacts between a tungsten tip and the superconducting heavy-fermion compounds. On lowering the temperature to below T sub(c) the contact resistance drops by delta R. Usually this change in resistance is interpreted by the Andreev-reflection process at the normal-supe...
