Physica A: Statistical Mechanics and its Applications, 1980, vol. 100, issue 3, 625-631

Abstract: This is a study of the equilibrium statistical mechanics of a mixed system of planar spins and Ising spins. The Ising spins σr are situated (one on each of the bonds connecting the planar spins sr so that the planar spins interact only via Ising spins. For a one-dimensional lattice the partition function and the two-spin correlation functions (〈σrσr1〉 and 〈Sr·Sr1〉) are calculated ex actly in terms of modified Bessel functions.
