金属间化合物CeNi2Al5是一种正交型致密近藤化合物，其磁转变温度为2.6K。我们用粉末样品和单晶样品进行了磁化强度和中子衍射测量，研究了CeNi2Al5的磁结构。结果表明，该磁结构为正弦波调制，传播矢量k=(1/2，2/5，1/12)。磁矩的最大幅值为1.54µB，其方向从b轴向a轴倾斜8度。
The intermetallic compound CeNi 2 Al 5 is an orthorhombic dense-Kondo compound with a magnetic transition temperature at 2.6 K. We have carried out magnetization and neutron diffraction measurements to study the magnetic structure of CeNi 2 Al 5 using a powder sample and a single crystalline sample. It is found that the magnetic structure is sine-wave modulated with a propagation vector k =(1/2,2/5,1/12). The maximum amplitude of magnetic moment is equal to 1.54 µ B and its direction is tilted 8 degrees from the b -axis toward the a -axis.
