Flat band driven itinerant magnetism in the Co-pnictides CaCo${}_2$As${}_2$ and LaCo${}_2$P${}_2$

D. Subires, M. García-Díez, A. Kar +12

Flat bands can induce strong electron correlation effects that help stabilize both magnetic and superconducting states. Here, we carry out angle-resolved photoemission spectroscopy…
