| 中文摘要 | The crystallographic and magnetic structures of Ho2Fe17-xAlxC (x = 4 and 7) were investigated by powder neutron diffraction at room temperature. The results indicate that both compositions are isostructural with Th2Zn17 (space group, R (3) over bar m). Aluminium substitutes for iron in three of the four Fe sites (18h, 18f and 6c in the hexagonal description of the rhombohedral cell) but not in 9d, and the fractional occupancies have been determined for both compositions. The carbon atoms occupy 9e sites. The saturation magnetization and Curie temperatures of samples with x in the range 0-7 are given; in the room-temperature magnetic structure of the phase with x = 4 the magnetic moments of all the atoms lie in the plane perpendicular to the (3) over bar axis, with the Fe moments being ferrimagnetically coupled to those of Ho. |
