The hyperfine interaction of /sup 165/Ho in the cubic Laves phase compounds Ho/sub 0.01/Gd/sub 1-x/Y/sub x/Ni/sub 2/ has been investigated by spin-echo NMR in the composition range 0 < x < 0.18. In the end compound (x = 0) a value of 9.5..mu../sub B/ is obtained for the holmium moment which indicates a 5% quenching by the crystalline electric field. Further quenching takes place with substitution of yttrium for gadolinium. The magnetization anisotropy of these compounds is weak. The substitution of 1-at.% Ho for Gd suffices to rotate the easy axis of magnetization in GdNi/sub 2/ from the <110> to the <100> direction. This direction remains the easy magnetization direction in all compounds studied. The transferred hyperfine interaction is long range and analysis of data indicates considerable participation of the d electrons in the hyperfine interaction in this series.
