description The effects of Mn element on the thermal stability, high frequency magnetic permeability, microstructure and magnetic domain of FeCuSiBNb alloys were studied utilizing DSC, XRD, TEM, MOKE, DC B-H loop tracer and impedance analyzer. With the addition of a small amount of Mn, the temperature interval between the first and second crystallization temperatures and the coercivity of the alloys remain almost constant, but the high frequency permeability and the interval of annealing temperature improve significantly. Compared with Mn-free alloys, the permeability of Mn-doped alloys at 10 kHz is increased by 36.5%, and the precipitation of Fe3B phase is suppressed. This good properties in the Mn-doped alloys can be attributed to the fact that Mn doping reduces the mean grain size, and thus it improves the uniformity of the magnetic domains, which decreases the pinning field of the nanocrystalline alloys.
