摘要

An overview of the crystal structures and physical properties of the recently discovered iron-platinum-arsenide superconductors, Ca₁₀(Pt_nAs₈)(Fe_2鈭?em>xPt_xAs₂)₅ ( and 4), which have a superconducting transition temperature up to 38聽K, is provided. The crystal structure consists of superconducting Fe₂As₂ layers alternating with platinum-arsenic layers, Pt_nAs₈. The upper critical field , hydrostatic pressure dependence of superconducting transition temperature , and normal-state magnetic susceptibility are reported.
