Abstract
A Monte Carlo sampling technique based on 2 x 2 rotations of the Heise nberg spin-1 Hamiltonian containing both anisotropic and next-nearest- neighbour (NNN) terMS has been attempted. Closed rings of six, eight, 10 and 12 spin-1 sites have been studied and the ground and the first excited states have been obtained. The validity of the procedure has a lso been tested using the spin correlation function for the ground sta te.
