Abstract

An overview of the crystal structures and physical properties of the recently discovered ironplatinumarsenide superconductors, Ca ₁₀(Pt _nAs ₈)(Fe _2-xPt _xAs ₂) ₅ (n=3 and 4), which have a superconducting transition temperature up to 38 K, is provided. The crystal structure consists of superconducting Fe ₂As ₂ layers alternating with platinumarsenic layers, Pt _nAs ₈. The upper critical field ^Hc2, hydrostatic pressure dependence of superconducting transition temperature ^Tc, and normal-state magnetic susceptibility are reported.
