Paper reporting flatband ferromagnetism in RbCo2Se2 is published in PRB, congrats to Jianwei!
Our paper on flat-band itinerant ferromagnetism in RbCo2Se2 is published in PRB: https://journals.aps.org/prb/pdf/10.1103/PhysRevB.103.165105 RbCo2Se2 is isostructural to the intercalated high Tc iron-based superconductor RbFe2Se2. Via a combined ARPES, neutron, transport, and DFT study, we identify the origin of the ferromagnetic
