Structural, thermodynamical and magnetic properties of Fe73.5−xSi13.5B9Cu1Nb3MnxFe73.5−xSi13.5B9Cu1Nb3Mnx amorphous alloys, with Mn content x=1,3–15x=1,3–15, were studied by means of X-ray diffraction (XRD), differential scanning calorimetry (DSC), Mössbauer spectroscopy (MS) and energy-dispersive X-rays (EDX), as-quenched and after annealing. The alloys with x≤7x≤7 suffer primary (above ∼∼550 °C) and secondary (below ∼∼680 °C) crystallisation, whereas the alloys with x≥9x≥9 only at ∼∼580 °C. Mn doping results in increase (for x≤7x≤7) and then (for x≥9x≥9) in decrease of grain size. The hyperfine field of the amorphous precursor and remainder substantially decrease with increase of Mn content x, whereas the fields in crystallites remain nearly independent of x . A paramagnetic component appears at x∼9x∼9 and grows with x.
