Abstract

and that N in Co in equilibrium alloys does not produce materials with significant magnetization and anisotropy. By contrast, our experiments identify new Co- N compounds with favorable magnetic properties including hexagonal Co3N nanoparticles with a high saturation magnetic polarization ( Js = 1.28 T or 12.8 kG) and an appreciable uniaxial magnetocrystalline anisotropy ( K1 = 1.01 MJ m- 3 or 10.1 Mergs per cm3). This research provides a pathway for uncovering new magnetic compounds with computational efficiency beyond the existing materials database, which is significant for future technologies.
