A magnetic core having an iron-based amorphous alloy that includes: a chemical composition with a formula FeaBbSicCd, where 81.5<a≦̸84, 12<b<17, 1≦̸c<5 and 0.3≦̸d≦̸1.0, numbers being in atomic percent, with incidental impurities, simultaneously having a value of a saturation magnetic induction equal to or exceeding 1.63 tesla, a Curie temperature greater than or equal to 315° C. and less than or equal to 360° C. and a crystallization temperature greater than or equal to 400° C. and less than or equal to 470° C. The core has low core loss and exciting power and is suited for transformers, electrical chokes, power inductors and pulse generation and compression devices.
