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...

description 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 volume fraction was observed at 0.12 ≤ x ≤ 0.18 and y = 0.06 in Ca(1−x)La(x)Fe(2)(As(1−y)P(y))(2). The superconducting phase of the present system seems to be not adjacent to an antiferromagnetic phase.
