摘要：

Magnetic measurements of R-Fe-B (R = rare earth) amorphous alloys show that magnetic anisotropy axes are correlated on the scale approximately 100 angstrom. The X-ray study of these materials does not reveal any positional correlations beyond the 10 angstrom scale. These observations support theoretical suggestions that the orientational order in amorphous systems can be much more extended than the positional order.
