Heat bath Monte Carlo simulations have been used to study a 12-state discretized Heisenberg model with a new type of random field on simple cubic lattices of size 128 × 128 × 128. The 12 states correspond to the [110] directions of a cube. The model has the standard nonrandom twospin exchange term with coupling energy J and a random field which consists of adding an energy hR to two of the 12 spin states, chosen randomly and independently at each site. We report on the case hR/J = 3, which has… Expand
