Abstract
It was shown that pulverization of the examined alloys cause a decrease of mean diameters of nanocrystallites, a change of the phase composition and affects magnetic properties. For the alloy with x=0.08 magnetization remanence at T=300 K increases about two times with remaining constant Hc while for x=0.12 Hc decreases from 1.16 t to 0.36 T. The observed effects were attributed to the phase structure changes and breaking of direct magnetic intergrain coupling
