An anisotropic integrable spin chain, consisting of spins s = 1 and 0305-4470/29/9/010/img1, is investigated . It is characterized by two real parameters 0305-4470/29/9/010/img2 and 0305-4470/29/9/010/img3, the coupling constants of the spin interactions. For the case 0305-4470/29/9/010/img4 and 0305-4470/29/9/010/img5 the ground-state configuration is obtained by means of thermodynamic Bethe ansatz. Furthermore, the low excitations are calculated. It turns out that apart from free magnon states being the holes in the ground-state rapidity distribution, there exist bound states given by special string solutions of Bethe ansatz equations (BAE) in analogy to . The dispersion law of these excitations is calculated numerically.
