Abstract

We present small angle neutron scattering measurements of the static structure factor S(q) of the binary fluid mixture water-lutidine imbibed into the porous glass Vycor as a function of temperature and composition. S(q) changes from a Lorentzian in the one phase region to a Lorentzian squared at the random field transition. The correlation length increases from ∼ 20 A in the one phase region to to ∼ 52 Å (≈ pore diameter) in the frozen domain state.
