使用斩波光谱仪和三轴光谱仪对金属间化合物 MnP 进行非弹性中子散射实验。在整个布里渊区的铁磁相中沿 a* 和 b* 轴观察到自旋波。观察到的自旋波的色散关系可以通过各向同性海森堡相互作用以及两个子晶格添加单个离子各向异性来很好地描述。
Inelastic neutron scattering experiments on an intermetallic compound, MnP, were performed by using a chopper spectrometer as well as triple axis spectrometers. Spin waves were observed in the ferromagnetic phase in the entire Brillouin zone along the a*- and b*-axes. The observed dispersion relations of spin waves were well described by an isotropic Heisenberg interaction adding a single ion anisotropy with two sub-lattices.
