摘要

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 Al and the atom 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 Curie temperatures of samples with x in the range 0～8 are investigated.
