In this paper we show that a strong magnetic anisotropy appears in exchange mixed+valence clusters containing orbitally degenerate metal ions. Combining an e4ective Hamiltonian approach with the technique of the irreducible tensor operators (ITO) and pseudoangular momentum representation we have sol
