ε-Fe3N: magnetic structure, magnetization and temperature dependent disorder of nitrogen / Leineweber, A. ; Jacobs, H. ; Hüning, F. ; Lueken, H. ; Schilder, H. ; Kockelmann, W.

  • ε-Fe3N has been investigated by time-of-flight neutron diffraction (temperature range 4.2–618 K) and SQUID magnetometry (2–700 K, B≤5 T). A ferromagnetic spin structure is observed with magnetic moments oriented perpendicular to the c-axis of the hexagonal nuclear structure. The magnetic saturation moment of iron is 2.2 μB at 4.2 K from neutron diffraction and 2.0 μB from magnetic measurements and decreases in a Brillouin-like manner on heating to TC=575 K. Above 450 K an increasing but reversible disorder of the nitrogen partial structure is observed.
