Abstract
We investigate via Monte Carlo simulations the multicritical behavior of Ising antiferromagnets in three dimensions. Even for ratios between the intrasublattice and intersublattice couplings as small as R=0.05, we find tricritical behavior and no evidence for a decomposition into a critical end point and a double critical end point as predicted by mean-field theories.
