摘要:
Magnetic properties of the single-crystalline Lu2Fe17-xMnx compounds, in which x=0, 0.5, and 2, with the Th2Ni17-type crystal structure are reported. The Lu2Fe17-xMnx compounds with x=0 and 0.5 are ferromagnets at low temperatures and antiferromagnets at high temperatures. The compound with x=2 is always a ferromagnet. The easy-plane magnetic anisotropy in the Lu2Fe17-x Mn-x ferromagnets drastically weakens with increase in Mn content up to x=2. The temperature dependence of the first magnetic anisotropy constant was obtained and compared with the single-ion model prediction. (C) 2010 Elsevier B.V. All rights reserved.
