TLDR
In this article, the Curie temperature of the R2Fe17-xAlx compounds was found to increase from TC=391K for the x=0 sample to TC=471 K for the X=3 sample.Abstract:
Compounds in the series Sm2Fe17-xAlx have been investigated. Samples with x=0, 1, 2, 3 and 4 have been shown to be single phased with the Th2Zn17 structure. The Curie temperature is found to increase from TC=391K for the x=0 sample to TC=471 K for the x=3 sample. Further substitution of Al for Fe decreased TC. X-ray diffraction studies of magnetic-field-oriented powders showed that alloys with x 2 exhibit easy axis anisotropy. The x=2 sample showed a mixture of easy plane and easy axis behaviour. This observation represents the first case of clear evidence for room temperature uniaxial anisotropy in the R2Fe17 compounds without the addition of interstitial nitrogen or carbon.read more

Perspectives in permanent magnetism
TL;DR: In this article, the authors reviewed recent developments in rare-earth permanent magnetism with emphasis on new materials, especially interstitially modified rare earth iron alloys which combine a high Curie temperature with large uniaxial anisotropy, and new nanostructures, including those which interleave hard and soft regions on the scale of the domain wall width of the hard phase.
