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 x2 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.Keywords
