Magnetocrystalline anisotropy of Y 2+x Co 1-y Fe y ) 17-2x intermetallic compounds

The pseudobinary solid solutions of Y 2+x (Co 1-y Fe y ) 17-2x intermetallic compounds with the hexagonal Th 2 Ni 17 type structure have been investigated in relation to their magnetocrystalline anisotropy. It was found from X-ray diffraction measurements on magnetically oriented powder samples that the sign of the anisotropy constant of the compounds changes at certain values of x and y . It is noted that in the compounds with small Fe content ( y\approx0 ) their stoichiometric character ( x ) plays an important role in determining the sign of the anisotropy constant.
