The individual site anisotropy model was applied to the Y(Fe1-xCox)11Ti, Y(Fe1-xCox)10Mo2
and YFe12-xVx compounds with the ThMn12 structure. Based on the relation between the CaCu5 and
ThMn12 structures, the results are discussed in comparison with those previously obtained for R(Co1-xFex)
5 and related compounds. ?? 1995.
