The crystallographic and magnetic structures of Ho_2Fe_9Ga_(8～x)Al_x(x=2,4 and 6)arestudied by powder neutron diffraction at room temperature.The atom fractional occupancies ofGa and AI and the atom magnetic moments of Ho and Fe are obtained by Rietveld analysisprogram.The magnetic structure of the phase with x=2 shows an easy-axis anisotropy and themagnetic moments of all atoms are parallel to c axis.The saturation magnetization and Curietemperatures of samples with x in the range 0～8 are investigated.
The crystallographic and magnetic structures of Ho_2Fe_9Ga_ (8~x) Al_x (x = 2,4 and 6) are studied by powder neutron diffraction at room temperature. The atom fractional occupancies of Ga and AI and the atom of magnetic moments of Ho and Fe are obtained by Rietveld analysis program. The magnetic structure of the phase with x = 2 shows an easy-axis anisotropy and the magnetic moments of all atoms are parallel to c axis. The saturation magnetization and Curietemperatures of samples with x in the range 0 to 8 are investigated.
