According to high energy X-ray diffraction measurements no significant changes were observed in a short range atomic order of amorphous ribbons Fe73.5-xMnxCu1Nb3Si13.5B9 (x=1 up to 15 at.%). Thermal stability of the as-prepared alloys was investigated by differential scanning calorimetry and by in situ X-ray diffraction measurements. The two-step crystallization process was revealed, crystallization temperatures Tx1 and Tx2 were influenced by Mn content (thermal separation between Tx1 and Tx2 completely vanished for x=9). Nanocrystalline state of annealed samples was confirmed by electron transmission microscopy. The influence of Mn substitution on magnetic properties was confirmed by thermomagnetic measurements.
