Abstract
We discuss the description of quantum magnetization in the super paramagnetic compound Fe using a generalization of the Lipkin-Meshkov-Glick Hamiltonian. We study the variation of the energy spectra and of the wave-functions as functions of the intensity of an external magnetic field along the three magnetic anisotropy axes.
