摘    要:通过Mossbauer谱等研究(Sm1-xYx)2Fe(17)Ny的磁性。结果表明:Sm次格子的单轴各向异性较强,对总的各向异性贡献起主导机制;Y原子的择优占位导致晶体结构的变化,而对各向异性的影响较小。

关 键 词:(Sm_(1-x)Y_x)_2Fe_(17)N_y,各向异性,择优占位,饱和磁矩,Mssbauer谱

Abstract:The magnetic properties of(Sm1-xYx)2Fe(17)Ny were studied by Mossbauer spectroscopy. The following conclusions were obtained:The uniaxial anisotropy of Sm sublattice is stronger and is the main mechanism of the total anisotropy; The preferential occupation of Y atom leads to the change of crystal structure and the influence on anisotropy is smaller.
Keywords:Sm_(1-x)Y_x)_2Fe_(17)N_y  anisotropy  preferential occupation  saturation atom moment  Mssbauer spectroscopy
