Motivated by recent experiments on the metamagnet FeBr2, anomalies
of the magnetization and the specific heat in the antiferromagnetic
phase of related spin models are studied systematically using
Monte Carlo simulations. In particular, the dependence of the
anomalous behavior on competing intralayer interactions, the
spin value and the Ising-like anisotropy of the
Hamiltonian is investigated.
Results are compared to experimental findings on FeBr2
