Superconductivity and magnetic and transport properties of single-crystalline CaK(Fe${}_{1-x}$Cr${}_x$)${}_4$As${}_4$

M. Xu, J. Schmidt, M. A. Tanatar +3

Members of the CaK(Fe${}_{1-x}$Cr${}_x$)${}_4$As${}_4$ series have been synthesized by high-temperature solution growth in single crystalline form and characterized by X-ray diffract…
