Amorphous structure and its thermal stability as well as magnetic properties of Fe 80– x Co x P 14 B 6 (20 ≤ x ≤ 40) glasses have been studied by X‐ray diffraction, non‐isothermal differential scanning calorimetry (DSC) and thermomagnetic (TMG) measurements. The Curie temperature increases with Co content, while the glass transition and crystallization onset temperatures decrease. As a result, for alloys x = 30, 32 and 35 at%, the transition into paramagnetic state take place close to glass transition temperature. However, for x = 40 at% the TMG curve, in the vicinity of magnetic transition temperature, is overlapped by ferromagnetic crystallization products. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
