arXiv:1712.02010

Abstract

We report superconductivity at 1.4K in the ternary SrPt $_{10}$ P $_{4}$ with a complex new structure. SrPt $_{10}$ P $_{4}$ crystallizes in a monoclinic space-group C2/c (\#15) with lattice parameters a= 22.9151(9) $A ˚$ , b= 13.1664(5) $A ˚$ , c=13.4131(5) $A ˚$ , and $β$ = 90.0270(5) $^{\circ}$ . Bulk superconductivity in the samples has been demonstrated through resistivity, ac susceptibility, and heat capacity measurements. High pressure measurements have shown that the superconducting T $_{C}$ is systematically suppressed upon application of pressure, with a dT $_{C}$ /dP coefficient of -0.016 K/GPa.
