摘要：

The fully frustrated triangular antiferromagnetic Ising model is found to order for higher spin values at finite temperatures. The ordered sublattices exhibit unsaturated magnetizations down to zero temperature, except for S = infinity, which saturates. These results are obtained by the recently developed hard-spin mean-field theory, which is highly successful for frustrated systems. The S = 1/2 case, as expected, and the S = 1 case show no finite-temperature ordering. Thus, ordering behavior is enhanced with increased spin values, in contrast to ferromagnetic systems.
