Polarised neutron; form factor; projection operator; NiRu alloy

Projection operator formalism has been applied to analyse magnetic structure amplitudes in Ni_1−xRu_x (x=0·027, 0·033 and 0·046) alloys. This method is suitable for metals and alloys as it does not assume any free ion form factor. A new prescription has been discussed for the local site moment and diffuse moment in this frame work. The results of the present analysis are compared with those obtained using form factor analysis.
