Near-room temperature ferromagnetic insulating state in highly distorted LaCoO2.5 with CoO5 square pyramids

Here, Zhang et al. succeed in creating a heavily distorted oxygen deficient film of lanthanum cobaltite. The new phase of LaCoO2.5 has several unique properties, most notably, a Curie temperature of 284 K, significantly larger than the films from which it was derived.
