BaTh $_{2}$ Fe $_{4}$ As $_{4}$ (N $_{0.7}$ O $_{0.3}$ ) $_{2}$ : An Iron-Based Superconductor Stabilized by Inter-Block-Layer Charge Transfer

arXiv:1908.03992 · doi:10.1007/s40843-019-9438-7

Abstract

Recently, An electron-doped 12442-type iron-based superconductor BaTh $_{2}$ Fe $_{4}$ As $_{4}$ (N $_{0.7}$ O $_{0.3}$ ) $_{2}$ has been successfully synthesized with high-temperature solid-state reactions on basis of a structural design. The inter-block-layer charge transfer between the constituent units of "BaFe $_{2}$ As $_{2}$ " and "ThFeAsN $_{0.7}$ O $_{0.3}$ " was found to be essential to stabilize the target compound. Dominant electron-type conduction and bulk superconducting transition at ~22 K were demonstrated.
