Short-range order in AgMn spin glass alloys : description from X-ray evidence

Further small angle X-ray diffusion experiments carried out on AgMn crystals containing a concentration of 1.4 at. % to 24 at. % Mn allow us to reject the description of S.R.O. based on the existence of ordered micro-domains. Instead, we carry out an analysis of the S.R.O. in term of Cowley parameters applicable to an homogeneous distribution of concentration, which we claim is the case for AgMn and probably CuMn.
