Flat band ferromagnetism in Pb $$_2$$ 2 Sb $$_2$$ 2 O $$_7$$ 7 via a self-doped mechanism
Abstract Electron systems with strong geometrical frustrations have flat bands, and their unusual band dispersions are expected to induce a wide variety of physical properties. However, for the emergence of such properties, the Fermi level must be pinned within the flat band. In this study, we perfo...
