English In the Ca1−x La x FeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x  =  0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at T N  =  120 K, well above the one at lower doping (0.15  <  x  <  0.27).Below the onset of long-range magnetic order at T N, the electrical...
