    The effects of substitutions of Ru for Fe and Ce for Lu on magnetic and thermal properties of Lu2Fe17 are studied by means of magnetization and specific heat measurements on single-crystalline samples of Lu2Fe17-xRux (x = 0, 0.5 and 1) and (Lu0.8Ce0.2)2Fe17. Both substitutions lead to the suppression of the low-temperature ferromagnetic phase present in Lu2Fe17, resulting in stabilization of the antiferromagnetism. An increase of the Sommerfeld coefficient is found for both substitution cases. The results are discussed taking into account the interatomic distance variation and the change of the electronic structure upon substitution. Thermal properties of Lu2Fe16.5Ru0.5 and (Lu0.8Ce0.2)2Fe17 are also studied across the metamagnetic transition restoring the F coupling.
