This contribution describes the reorientation of the magnetization of thin ferromagnetic Heisenberg films as function of the temperature and/or an external field. Working in a rotating frame allows an exact treatment of the single-ion anisotropy when going to higher order Green's functions. Terms due to the exchange interaction are treated by a generalized Tyablicov (RPA) decoupling.
