Amorphous Fe100-a-b P a M b foil, preferably in the form of a free-standing foil, process for its production by electrodeposition or electroforming of an aqueous plating solution, and its uses as a constitutive element of a transformer, generator, motor, pulse applications and magnetic shieldings. A is a real number ranging from 13 to 24, b is a real number ranging from 0 to 4, and M is at least one transition element other than Fe. The amorphous Fe100-a-b P a M b foil has the properties of being amorphous as established by the X-ray diffraction method, an average thickness greater than 20 micrometers, a tensile strength in the range of 200-800 MPa or higher, a high electrical resistivity of over 120 µ.OMEGA.cm, and at least one of a high saturation magnetization (B s) greater than 1,4 T, a low coercive field (Hc) of less than 40 A/m, a low hysteresis loss (W60), at power frequencies (60 Hz), and for a peak induction of at least 1,35 T, of less than 0,65 W/kg, and a high relative magnetic permeability (B/µ0H), for low values of µ0H, greater than 10000.
