Abstract
Specific heat, magnetic susceptibility, and resistivity were measured on polycrystalline samples of U(Be1−xBx)13 with 0≤x≤5.2×10−3. Small amounts of B greatly affect the specific-heat discontinuity at the superconducting phase transition in UBe13, while only weakly decreasing the superconducting transition temperature. The presence of B impurities also influences the resistivity. These observations are discussed in terms of possible impurity-induced changes in the symmetry and/or pairing interaction of the superconducting state in UBe13.
