Abstract
From the paramagnetic critical neutron scattering of Au0.82Fe0.18 we d erive the absolute values of the neutron bulk susceptibility chi(q=0)( T). The excellent agreement between chi(q=0)(T) and the susceptibility , measured with a Faraday balance, validates our analysis, in the fram e of the Omstein-Zernicke formalism, and the resulting enhancement of the critical correlations by the disorder.
