Abstract
We show that the solutions of the Yang--Baxter equation invariant under the action of the Yangian lead to inhomogenous vertex models. Starting from a four dimensional representation of we obtain an integrable family of coupled Heisenberg spin- chains. Some thermodynamical properties of this model are studied by means of the algebraic Bethe Ansatz.
