We present antiferromagnetism as a mechanism capable of modifying substantially the phase diagram and the
critical behaviour of statistical mechanical models. This is particularly relevant in four dimensions, due to the
connection between second order transition points and the continuum limit as a quantum field theory.
We study three models with an antiferromagnetic interaction: the Ising and the 0(4) Models with a second
neighbour negative coupling, and the RP^(2) Model. Different conclusions are obtained depending on the model.
