Quantitative understanding of thermal stability of α′′-Fe16N2

Abstract

The thermal stability of α''-Fe16N2, which attracts much interest because of its superior magnetic properties featuring a large magnetocrystalline anisotropy (Ku ~ 1 × 10(7) erg cm(-3)) and a large saturation magnetization (Ms ~ 234 emu g(-1)), though unfortunately thermally unstable, has been quantitatively studied.
