摘要：

The spin correlation range xi in the amorphous random anisotropy magnets Dy7-xYxNi3 has been measured by small-angle neutron scattering. xi is typically a few atomic spacings, as expected for a speromagnet. We suggest that previous estimates of xi (similar to 15 nm), consistent with correlated speromagnetism, may have resulted from magnetic scattering associated with microcrystalline impurities in the amorphous matrix.
