摘要：

The compounds Lu2Fe17-xMnx, in which x = 0-2, with the Th2Ni17-type crystal structure were synthesized. Their structural and magnetic properties are presented. The Lu2Fe17-xMnx compounds with x = 0-0.5 are ferromagnets at low temperatures and antiferromagnets at high temperatures. Their temperature of "ferromagnet-antiferromagnet" phase transition surprisingly increases very fast from 135 to 253 K with a growing content of Mn, whereas Neel temperature stays practically unchanged (similar to 278 K) and is close to Curie temperature T-C = 287 K for the compound with x = 0.7. The compounds from the range x = 0.7-2 are ferromagnets only with a near constant T-C(x) value. (C) 2008 Elsevier Ltd. All rights reserved.
