在78 K和4.2 K下对ndb6多晶样品进行了中子衍射测量。该材料具有反铁磁序,尼尔温度为8.6 K。从衍射数据推断出的磁性结构表明单晶在一个方向上有简单的反铁磁加倍。基于这种结构,对数据进行了剖面分析,得出在4.2 K时的磁矩为每钕离子1.74玻尔磁子。
Neutron diffraction measurements were made on a polycrystalline sample of NdB6at 78 and 4.2 K. This material orders antiferromagnetically with a Neel temperature of 8.6 K. The magnetic structure inferred from the diffraction data indicates a simple antiferromagnetic doubling of the unit cell in one direction. Based on this structure a profile analysis of the data gives a magnetic moment at 4.2 K of 1.74 Bohr magnetons per neodymium ion.
