Abstract: | 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−xMnx 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. |
