Enhancement of the Curie temperature in single crystalline ferromagnetic LaCrGe by electron irradiation-induced disorder
E. H. Krenkel, M. A. Tanatar, M. Konczykowski +5
LaCrGe has attracted attention as a potential candidate for studies of quantum phase transitions in a ferromagnetic material. The application of pressure avoids a quantum criti…
Electron irradiation reveals robust fully gapped superconductivity in LaNiGa
