Abstract
We report a Monte Carlo study of a classical Type I antiferromagnet in an fcc lattice with isotropic spin-spin interactions. In accord with recent predictions, the ordered spin structure is a single-k state in low fields and a triple-k configuration in high fields. Thermal fluctu ations stabilize the up-up-up-down form of the triple-k structure over a finite field interval.
