Abstract
- The effect of partial replacement of Y site with Ca or Ba site with Sr on the thermal and electrical properties of YBa2Cu3O7−δsuperconductors was investigated. For Y(Ba1−XSrX)2Cu3O7−δsystem, the characteristic enhancement of the thermal conductivity κ(T) below the transition temperature Tcwas decreased more slowly by substitution than that for (Y1−XCaX)Ba2Cu3O7−δsystem. Electron-phonon interaction in these systems were discussed based on the phonon heat conduction model under the weak coupling d-wave energy gap.
