Abstract
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 Néel temperature stays practically unchanged (∼278 K) and is close to Curie temperature TC=287K for the compound with x=0.7. The compounds from the range x=0.7-2 are ferromagnets only with a near constant TC(x) value.
