ABSTRACT: An overview of the crystal structures and physical properties of the recently
discovered iron-platinum-arsenide superconductors, Ca10(PtnAs8)(Fe2-xPtxAs2)5
(n = 3 and 4), which have a superconducting transition temperature up to 38 K,
is provided. The crystal structure consists of superconducting Fe2As2 layers
alternating with platinum-arsenic layers, PtnAs8. The upper critical field Hc2,
hydrostatic pressure dependence of superconducting transition temperature Tc,
and normal-state magnetic susceptibility are reported.
ABSTRACT: We report superconductivity in novel iron-based compounds
Ca10(PtnAs8)(Fe2-xPtxAs2)5 with n = 3 and 4. Both compounds crystallize in
triclinic structures (space group P-1), in which Fe2As2 layers alternate with
PtnAs8 spacer layers. Superconductivity with a transition temperature of 38 K
is observed in the n = 4 compound with a Pt content of x ~ 0.36 in the Fe2As2
layers. The compound with n = 3 exhibits superconductivity at 13 K.
