Emergence of superconductivity at 45 K by lanthanum and phosphorus co-doping of CaFe(2)As(2)

Co-doping of lanthanum and phosphorus in CaFe(2)As(2) induces superconductivity at 45 K. This superconducting transition temperature is higher than the 38 K transition in Ba(1−x)K(x)Fe(2)As(2), which is the maximum found thus far among the 122 phases. Superconductivity with a substantial shielding v...
