Em. Chudnovsky et J. Tejada, EVIDENCE OF THE EXTENDED ORIENTATIONAL ORDER IN AMORPHOUS-ALLOYS OBTAINED FROM MAGNETIC MEASUREMENTS, Europhysics letters, 23(7), 1993, pp. 517-522
Magnetic measurements of R-Fe-B (R = rare earth) amorphous alloys show
that magnetic anisotropy axes are correlated on the scale approximate
ly 100 angstrom. The X-ray study of these materials does not reveal an
y positional correlations beyond the 10 angstrom scale. These observat
ions support theoretical suggestions that the orientational order in a
morphous systems can be much more extended than the positional order.
