摘要：
The domain structure of the nanocrystalline Fe91Zr7B2 alloy at the optimum soft magnetic state was studied by means of magnetic force microscopy (MFM). Curved domains separated by 180 degrees Malls were observed. The domain wall width (similar to pi L-ex, where L-ex is the exchange correlation length) was estimated to be less than 2 +/- 0.3 mu m front the MFM image. This result is consistent with the L-ex value (similar to 0.5 mu m) evaluated from the measured magnetic properties. These results reveal that the excellent soft magnetic properties are due to the averaging of the effects of the magnetocrystalline anisotropy (K-1) over the order of 10(4) grains.
