Abstract
We present a systematical study on the roles of interactions among electron correlation, electron-phonon coupling, and spin-orbit coupling in the isovalent Pd-substituted superconductor SrPt3P. By using the solid state reaction method, the Pd element with the 4d orbital was successfully substituted in the strong spin-orbit coupling superconductors Sr(Pt1−xPdx)3P. As increasing the isovalent Pd concentrations without introducing any extra electron/hole carriers, the superconducting transition temperature Tc decreases monotonously. In addition, combining the data of resistivity and specific heat, as well as electronic band structure calculations, we found that the electron correlation is enhanced while the electron-phonon coupling and the spin-orbit coupling are suppressed by Pd substitution. Our results may provide significant insights in the natures of the interplay among the electron correlation, electron-phonon coupling, and spin-orbit coupling in superconductivity, and may also pave a route for understanding the mechanism of superconductivity in heavily 5d-based superconductors.
