摘要

The influence of magnetic field annealing and Cu content on saturation magnetostriction (lambda _{s}) , effective magnetic anisotropy (< {textit {K}} >) , and temperature dependence of initial permeability ( (mu _{i}) (T) curves) for nanocrystalline Fe39.4−xCo40Nb2.6Si9B9Cux ( (x=0.5) , 1, 1.5) alloys was investigated. The (lambda _{s}) and italic>K (lambda _{s}) , which is due to the rearrangement of random oriented magnetic domain along applied field direction. The increase of italic>KK (_{u}) under magnetic field annealing, which can be explained in terms of the directional atomic pair ordering theory. In addition, the inverse dependence between (mu _{i}) and italic>K39.4−xCoNb2.6Si9B9Cux ( (x=0.5) , 1, 1.5) alloys; the reason of which was also analyzed.
