Some observations on heavy fermion superconductivity in UBe13

  • G. R. Stewart

Recently it has been discovered that very slight substitution of Cu for Be in UBe13 depresses superconductivity below 0.050 K. We have measured the low-temperature specific heat of UBe12.94 Cu0.06(Tc<0.050 K) and found that the heavy fermion, condensed phase present in UBe13 appearsunaltered in the copper-substituted material. Therefore, the presence of high-mass electrons is not directly correlated with superconductivity in UBe13.
