摘要：
The crystallographic and magnetic structures of Ho-2 Fe-9 Ga-6 and Ho-2 Fe-9 Ga-6 Al-2 were studied by powder neutron diffraction at room temperature. The atom fractional occupancies of Ga and Al and the magnetic monents of Ho and Fe were obtained by using Rietveld analysis program. The magnetic structures of the two samples show an easy-axis anisotropy, with the Fe magnetic moment being ferrimagnetically coupled to those of Ho.
