Kagome materials host nearly dispersionless electronic bands, but an ideal flat band close to the Fermi level is difficult to realize. Here the authors report evidence for a flat band near the Fermi level and flat-band-originated ferromagnetic fluctuation induced by orbital selective correlations in Sc3Mn3Al7Si5.
