FIELD: electrical engineering; saturable reactors and pulse transformers. SUBSTANCE: proposed spiral ribbon core made of magnetically soft amorphous alloy containing iron, nickel, silicon, and boron has following proportion of alloy components, atom percent: nickel - 0.1-10.0; silicon - 7.0-11.0; boron - 10.0-16.0; iron - the rest; Br/B800 in magnetic core is higher than 0.8, where Br is residual flux density; B800 is magnetic flux density at magnetic field strength of 800 A/m. As an alternative, core may have Br/B800 < 0,1. EFFECT: improved response to heat treatment in magnetic field at high magnetic flux density. 2 cl, 1 dwg, 1 tbl, 1 ex
