Spintronic materials based on main-group elements
Abstract
Recently, half-metallic magnetism was predicted for rubidium sesquioxide at relatively high temperatures. Here, we present density-functional calculations on related potassium and caesium oxides as well as hypothetical continuous series. Finally, we consider ammonium sesquioxide and estimate a Curie temperature of 250 K. All these half-metals posses band gaps for the majority spin direction.
