Single molecule magnets and the Lipkin-Meshkov-Glick model

We discuss the description of quantum magnetization in the super paramagnetic compound Fe8 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 thr...

Sumario:We discuss the description of quantum magnetization in the super paramagnetic compound Fe8 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.
