From Charge to Orbital Ordered Metal-Insulator Transition in Alkaline-Earth Ferrites

Mr. Yajun Zhang, Mr. Michael Schmitt, Mr. Alain Mercy +2

While CaFeO${}_3$ exhibits upon cooling a metal-insulator transition linked to charge ordering, SrFeO${}_3$ and BaFeO${}_3$ keep metallic behaviors down to very low temperatures. Moreove…
