Oxide glass crystallization method obtained submicrocrystalline rapidly quenched alloys and amorphous structure. It is shown that vitrified grinding in distilled water, compared to grinding in toluene resulted in a slight decrease in the coercive force (from 9 to kilooersted 8,2 kilooersted) and increase residual induction (from 0,75 kilogauss to 1,25 kilogauss, respectively. After annealing at presszagotovki 1050 C at 30 min following magnetic properties obtained
