摘要
We review the symmetrical spin clusters for which the Heisenberg exchange Hamiltonian can be exactly diagonalized by simple recoupling techniques of angular momenta. This procedure, already applied to n ≤ 4 spin clusters, is systematically extended up to 9 spins. It is shown that it can also be used for ions with different isotropic g values. A simplified expression of the magnetic susceptibility is derived and its validity is discussed.
