Structural and magnetic phase transitions in Ca${}_{0.73}$La${}_{0.27}$FeAs${}_2$ with electron overdoped FeAs layers

Shan Jiang, Chang Liu, Huibo Cao +15

We report a study of the Ca${}_{0.73}$La${}_{0.27}$FeAs${}_2$ single crystals. We unravel a monoclinic to triclinic phase transition at 58 K, and a paramagnetic to stripe antiferromagnet…
