Show affiliationsThe structure and magnetic properties of R2Fe17-xAlx compounds with R=Sm and with R=Tb were studied. The compounds have a rhombohedral ThsZn17-type structure. The Curie temperature TC is found first to increase and then to decrease with increasing x. The substitution of Al has a significant effect on the magnetic anisotropy of R2Fe17-xAlx compounds. A small amount of Al substitution in Sm2Fe17 induces uniaxial anisotropy and a further substitution results in a change in the easy-magnetization direction from c axis to basal plane, whereas an opposite change in the magnetocrystalline anisotropy has been observed in the alloys of Tb2Fe17-xAlx. The samples of Tb2Fe17-xAlx with x>or=6 exhibit an easy c axis anisotropy.
