Abstract

Different structural states, namely microcrystalline, submicrocrystalline, nanocrystalline (each with a different set of grain sizes) and amorphous ones, in magnetically soft materials intended for fabricating sensitive elements in high-tech equipment are considered. The effects of the structural state of Fe5Co70Si15B10, Fe60Co20Si5B15, Co81.5Mo9.5Zr9, and Fe73.5 − x Co x Cu1Nb3Si13.5B 9 (x = 0, 10, 20, 30 at.%) amorphous alloys on their magnetic characteristics in different nanocrystallization conditions are analyzed. The correlation of the peculiarities of the fine structure and the grain sizes in the alloys under study with their magnetic parameters and informative parameters of the Barkhausen effect is shown.
