Summary:The thermal stability of α′′-Fe 16 N 2 , which attracts much interest because of its superior magnetic properties featuring a large magnetocrystalline anisotropy ( K u ∼ 1 × 10 7 erg cm −3 ) and a large saturation magnetization ( M s ∼ 234 emu g −1 ), though unfortunately thermally unstable, has been quantitatively studied. The thermal stability of α′′-Fe 16 N 2 , which has a large magnetocrystalline anisotropy ( K u ∼ 1 × 10 7 erg cm −3 ) and a large saturation magnetization ( M s ∼ 234 emu g −1 ), though unfortunately thermally unstable, has been quantitatively studied.
