Description
| - The antiferromagnetic state observed in Lu2Fe17 at elevated temperatures is stabilized down to the ground state in (Lu0.8Ce0.2)2Fe17 and Lu2Fe16.5Ru0.5. The Néel temperature TN decreases from 275 K in Lu2Fe17 to 247 K and 208 K in (Lu0.8Ce0.2)2Fe17 and Lu2Fe16.5Ru0.5, respectively. Both compounds exhibit the easy-plane magnetic anisotropy and a metamagnetic transition at fields below 1 T. External pressure pushes the transition towards higher field and reduces the magnetization as well as TN to 234 K and 185 K for (Lu0.8Ce0.2)2Fe17 and Lu2Fe16.5Ru0.5, respectively, under pressure 0.8 GPa. The pressure and the substitution effects can be understood in terms of exchange interaction varying strongly with changes of the lattice parameter c for (Lu0.8Ce0.2)2Fe17, while for Lu2Fe16.5Ru0.5, the change of magnetic structure occurs due to weakening of the positive exchange interaction as a result of reduction of the Fe magnetic moments at 12k sites.
