The manganese nitrides η‐Mn3N2 and θ‐Mn6N5 + x: nuclear and magnetic structures

Energy-dependent contrast in atomic-scale spin-polarized scanning tunneling microscopy ofMn3N2(010): Experiment and first-principles theory

“…The Mn atoms of the highly bulk-like surface have magnetic moments which alternate in a row-wise aFM arrangement. 10,12 Bulk measurements show the corresponding layer-wise aFM structure with magnetic moments of Mn1 and Mn2 which are each close to ∼ 3.5 µ B , 13,14 and bulk theoretical calculations are in good agreement. 15 SP-STM corrugation profiles in general are found to contain both magnetic and non-magnetic information.…”

Atomic-scale structure of η-phase Mn3N2(010) studied by scanning tunneling microscopy and first-principles theory

“…It is known from previous bulk studies that manganese nitride has different bulk phases, including θ (MnN), η (Mn 3 N 2 ), ε (Mn 4 N), and ζ (Mn 5 N 2 , Mn 2 N, and Mn 2 N 0.86 ). [11][12][13][14][15][16][17][18][19][20][21] Both structural and magnetic measurements have been reported for most of these bulk phases, and particular attention has been paid to the θ-MnN, η-Mn 3 N 2 , and ε-Mn 4 N. For the applications of this material, it is important to investigate the possibility of epitaxial growth. The control of the phases, and therefore the magnetic properties and orientations of manganese nitride grown on MgO(001) using molecular beam epitaxy (MBE), was reported by Yang et al recently.…”

Annealing-dependent magnetic depth profile inGa1−xMnxAs

“…This leads to consideration of a different interpretation, that the free surface features of the annealed film indicate the presence of a compound with a SLD profile very similar to that of GaAs, such as antiferromagnetic θ -MnN. 25 Therefore, it is possible that MnN or a related compound may have formed at the surface during annealing in nitrogen. Since PNR cannot distinguish between these two possible interpretations, investigations using other methods will be required to fully resolve this issue.…”
