Abstract
The spin correlation range xi in the amorphous random anisotropy magne ts 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 w ith correlated speromagnetism, may have resulted from magnetic scatter ing associated with microcrystalline impurities in the amorphous matri x.
