In Ce based heavy fermion systems the hybridization of the 4f orbital of the Ce ion and the conduction band lead to unconventional phenomena. The aim of this thesis is to investigate and compare the magnetism on a microscopic scale within the heavy fermion families CeT2X2 (X = Si, Ge) and CeTIn5. Neutron scattering was used as the experimental method. In this thesis, the magnetic phase diagram as well as the magnetic order is determined. Additionally, the spin dynamic in zero magnetic field as well as depending on temperature and magnetic field is investigated.
