中文摘要	Nanocrystalline Mn, Mn4N and Mn2N0.86 are prepared by homogenization and nitrogenation of as-milled Mn powders under different conditions. Due to uncompensated surface spins, nanocrystalline Mn exhibits weak ferromagnetism, Mn4N displays ferrimagnetism, while Mn2N0.86 dominant antiferromagnetism. The structural evolution of Mn -> Mn4N -> Mn2N0.86 is interpreted as N atoms being in different percentages of the octahedral interstices of different Mn arrangements. In terms of the distances between Mn atoms with different atomic configurations of Mn(N) compounds, we think that the large discrepancy between the second-nearest distances of Mn4N and Mn2N0.86 leads to their different magnetism.
