This paper presents the results of research on the magnetic saturation polarisation, as a function of temperature, for rapidly-cooled iron alloys with an amorphous structure. The rapidly-cooled Fe-based amorphous alloys are characterised by good magnetic properties. The Curie temperature is one of the main parameters that determine the stability of the ferromagnetic properties of such alloys. The tested materials met the assumptions of Heisenberg's theory; therefore, the critical factor, β = 0.36, was used to determine the Curie temperature. It was found that both of the tested alloys have one Curie temperature pertaining to the amorphous matrix - which proves their effective homogenisation.
