CeCu2Ge2 (CCG) is the isostructural magnetic counterpart of archetypal unconventional superconductor CeCu2Si2 (CCS). The understanding of the magnetic interactions in CCG promises to grasp the magnetic properties of CCS, and in a further step to magnetically mediated superconductivity. CCG orders AF below 4.2K (AF1) with an (hhl) propagation vector, which is revealed in vertical field along c. At 7.5T, a second AF phase (AF2) develops with a slightly changed propagation vector. Increasing field, all magnetic reflection decrease. Above 12.5T, no magnetic reflection are observed in the (hhl) scattering plane. Therefore, the nature of AF3 is still unknown. We expect the existence of an additional set of reflections (h –h l) having a different field dependence. Indeed, in horizontal field, magnetic reflections increase with field. Using HFM/EXED, we will track the field dependence of these reflections, find the AF2/AF3 phase transition and AF3 magnetic structure.
