We report new measurements of the normal-state electrical resistances of several high-Tc (∼ 20 K) A-15 structure superconductors. It is found that the resistances are linear functions of T2 from Tc to 40 K. Analysis of available lattice heat-capacity data on the same materials shows that it also varies as T2 over the same temperature interval. These observations suggest that the T2 resistivity is due to electron-phonon scattering. This interpretation is supported by the results of a model calculation for the temperature dependence of the resistivity and the lattice-heat capacity of Nb3Sn. © 1977 The American Physical Society. |
