Abstract
We report ESR measurements in UBe13 doped with 1000 ppm Gd, at temperatures down to 0.4 K, which is well below the superconducting transition temperature of this heavy fermion system. Our most important result is the observation that, within the experimental error, the Knight shift of the local Gd moments does not decrease below the normal-state value. The possible implications of this result for the nature of the superconductivity are discussed.

One of the most intriguing aspects of the physics of heavy fermion systems is the fact that some of these compounds exhibit a transition to a superconducting phase
Summary
Suhl We report ESR measurements in UBel 3 doped with 1000 ppm Gd, at temperatures down to 0.4 K, which is well below the superconducting transition temperature of this heavy fermion system. Our most important result is the observation that, within the experimental error, the Knight shift of the local Gd moments does not decrease below the normal-state value. In this paper we report ESR measurements in UBe~3 doped with 1000 ppm Gd impurities and discuss several implications of the results.
