We present, for ferrous halogenides, FeCl2, FeBr2, FeI2, the magnetization isotherms obtained, at low temperature, in a perpendicular magnetic field (static and pulsed fields). These experimental results show a divergence from the linear magnetization law. We give a natural interpretation of our results by using a rigorous treatment of a theoretical model in which we consider an assembly of triplet ions with a single ion uniaxial anisotropy, the magnitude of which is of the same order as the intralayer ferromagnetic exchange interaction (J1) and the intralayer antiferromagnetic one (J2) (molecular field-approximation). This study allows us to calculate the divergence from the linear law for all values of D, J1 and J2 and shows the fundament...
