<p>Amorphous Fe<SUB>100-a-b</SUB>P<SUB>a</SUB>M<SUB>b</SUB> 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 Fe<SUB>100-a-b</SUB>P<SUB>a</SUB>M<SUB>b</SUB> 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 200-1100 MPa, an electrical resistivity of over 120 µOcm, and at least one of a high saturation induction (Bs) greater than 1.4 T, a coercive field (Hc) of less than 40 A/m, a 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 relative magnetic permeability (B/µ0H) greater than 10000, for low values of µoH.</p> |
