Near-room-temperature ferromagnetism in pressurized SrCo2P2

SrCo2P2 undergoes a pressure-induced collapsed-tetragonal (cT) phase transition transition-driven by interlayer pnictogen bonding resulting in a remarkable near room temperature ferromagnetic ordering (TC up to 260 K) in the cT phase.

Accurate calculation of rare-earth magnetic anisotropy

Enforcing Hund’s rules in density functional theory (DFT) calculations is necessary for reliable modeling of rare-earth magnetic anisotropy (MA). Scientists at Ames National Laboratory and George Mason University collaborated to identify and address the most fundamental challenge in accurately modeling rare-earth MA within DFT.
