Abstract
We develop a general method to study inhomogeneous liquids in an exter nal field using orthogonal polynomials tailored to the one-body densit y. The procedure makes integral equation calculations of these systems no more difficult than those of ordinary homogeneous molecular fluids . We apply this method to the ferromagnetic Heisenberg spin fluid in a magnetic field using a ''reference'' version of the Zerah-Hansen clos ure, with no further approximations. Comparison with simulation shows this integral equation procedure yielding nearly exact results.
