Magnetic properties of the hypothetical compound YFe5

The magnetic properties of the hypothetical compound YFe5 are obtained by e xtrapolating the values of lattice constants, saturation magnetizations, M- s, and Fe-57 hyperfine fields, B-eff, for Y(T1-xFex)(5) (T = Co and Ni). Fo r the hypothetical compound YFe5. the average Fe moment and Fe-57 hyperfine fields are almost consistent with the estimated values based on an interpo lation of the concentration dependence of the Y-Fe compounds assuming that the values of M-s and the average B-eff show a maximum at x = 0.7 and 0.81, respectively.
