The classical limit of the effective antiferromagnetic Heisenberg Hamiltonian has been investigated on the series of free clusters (molecules) of C_{N} (N = 32, 44, 50, 58, 60,, 70 and 84). The valley structures of the frustrated ground states were determined. Moreover, the probability distributions of the spin correlation functions were calculated. |
