Abstract

SrPt₂As₂ is a novel arsenide superconductor, which crystallizes in the CaBe₂Ge₂-type structure as a different polymorphic form of the ThCr₂Si₂-type structure. SrPt₂As₂ exhibits a charge-density-wave (CDW) ordering at about 470K and enters into a superconducting state at T_c = 5:2K. The coexistence of superconductivity and CDW refers to Peierls instability with a moderately strong electron-phonon interaction. Thus SrPt₂As ₂ can be viewed as a nonmagnetic analog of iron-based superconductors, such as doped BaFe₂As₂, in which superconductivity emerges in close proximity to spin-density-wave ordering.
