TLDR
In this article, the properties of (Sm 0.5Tb0.5)2Fe17−xGax have been investigated and the easy direction of magnetization is in the ab plane up to x=5 and changes along the c axis for x=7.Abstract:
Magnetic properties of (Sm0.5Tb0.5)2Fe17−xGax [mentioned subsequently as SmTbFe17−xGax] have been investigated. All the compounds have formed in rhombohedral Th2Zn17 structure with traces of α‐Fe. The saturation magnetization decreases with increasing x and is attributed to the modification of the density of states of 3d band due to the low lying 3p band of Ga. The increase of Curie temperature up to x=3 and subsequent decrease is explained on the basis of band narrowing. The easy direction of magnetization is in the ab plane up to x=5 and changes along the c axis for x=7.read more

TL;DR: In this article, the Curie temperature of Fe, Co and Ni as well as of their compounds with Y (including Y2Fe14B) are calculated by including the effects of spin fluctuations in the long wavelength limit via a renormalisation of Landau coefficients.

TL;DR: This paper showed that silicon preferentially occupies the 18h site in the Nd 2 Fe 17 structure, the site with the most neodymium near neighbors, which is surprising because conventional arguments would suggest that replacement of iron on the 6c site, which has a very short iron to near-neighbor iron bond length, would yield an increase in the Curie temperature.
