摘要：Co-doping of lanthanum and phosphorus in CaFe₂As₂ induces superconductivity at 45 K. This superconducting transition temperature is higher than the 38 K transition in Ba_{1− x}K _x Fe₂As₂, 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 Fe₂(As_{1− y}P _y )₂. The superconducting phase of the present system seems to be not adjacent to an antiferromagnetic phase.
