通过磁性测量、M ssbauer谱和中子衍射研究了室温下Pr6 Fe13Ge的磁结构 .磁性原子集中分布在z=0和z=1 / 2镜面的两侧 ,被z=1 / 4 ,3/ 4处的非磁性原子分割成M(磁性 ) /NM(非磁性 ) /M(磁性 )排列的三明治结构 .磁性层M内磁矩为共线铁磁耦合 ,磁矩方向少量偏离ab面 ,形成小的c轴方向的分量 ;层与层之间 ,ab面内的磁矩分量为反铁磁耦合 ,而c轴方向的分量为铁磁耦合
The magnetic structure of Pr6Fe13Ge at room temperature was investigated by magnetic measurements, M ssbauer spectroscopy and neutron diffraction. The magnetic atoms were concentrated on both sides of z = 0 and z = 1/2 mirrors and were z = 1/4, 3/4 (Magnetic) / NM (non-magnetic) / M (magnetic) arranged sandwich structure of the magnetic layer M magnetic flux within the collinear ferromagnetic coupling, a small amount of magnetic moment away from the ab plane, the formation of small Component in the c-axis direction; the magnetic moment component in the plane ab between the layer and the layer is anti-ferromagnetic coupling and the component in the c-axis direction is the ferromagnetic coupling
