Ferromagnetic ε-Fe(2)MnN: High-Pressure Synthesis, Hardness and Magnetic Properties
The iron manganese nitride Fe(2)MnN was obtained by high-pressure–high-temperature synthesis from ζ-Fe(2)N and elemental Mn at 15(2) GPa and 1573(200) K. The phase crystallizes isostructural to binary ε-Fe(3)N. In comparison to the corresponding binary iron nitride, the microhardness of ε-Fe(2)MnN i...

description | The iron manganese nitride Fe(2)MnN was obtained by high-pressure–high-temperature synthesis from ζ-Fe(2)N and elemental Mn at 15(2) GPa and 1573(200) K. The phase crystallizes isostructural to binary ε-Fe(3)N. In comparison to the corresponding binary iron nitride, the microhardness of ε-Fe(2)MnN is reduced to 6.2(2) GPa. Above about 800 K the ternary compound decomposes exothermally under loss of nitrogen. ε-Fe(2)MnN is ferromagnetic with a Curie temperature of roughly 402 K. |
