中文摘要	The influence of Mn substitution for Fe on the structure and magnetic properties of Pr2Fe17-xMnx compounds with 0 less than or equal to x less than or equal to 9 was investigated. X-ray diffraction indicates that all samples are single phase with the rhombohedral Th2Zn17-type structure. The unit cell volume V remains nearly constant with increasing manganese content up to x=2, then increases linearly at a rate of about 2.5 Angstrom(3) per Mn atom up to x=8 and there is a large increase of cell volume at x=9. The Curie temperature increases a little from 298 K at x=0 to 308 K at x=1, and then decreases to 37 K at x=9 quickly. The saturation magnetization at 5 K was found to decrease monotonously with increasing Mn concentration. The thermal magnetization curves M(T) of the compounds with x=1-9 show a strong decrease below T-C with decreasing temperature. Also it presents considerable magnetic hardness at low temperature. This can be attributed to the presence of narrow Bloch walls. (C) 1999 American Institute of Physics. [S0021-8979(99)05621-2].
