      abstract     = {Heavy-fermion compounds, high-Tc cuprates or iron pnictides
                      are characterized by adja-cent properties and a rich
                      magnetic phase diagram with unconventional or competing
                      statesat low temperatures. CeCu2Ge2, the counterpart of the
                      heavy-fermion superconductorCeCu2Si2, exhibits an
                      incommensurate antiferromagnetically long-range ordered
                      ground statewith τ1 = (0.28 0.28 0.54) up to TN = 4.1 K
                      which is strongly affected by a screening of the
                      Ce4f-moments by conduction electrons expressed by a Kondo
                      temperature ofTK = ( 6–10) K. The similar energy scales of
                      the magnetic exchange and the Kondo effect result in a
                      complexmagnetic phase diagram with the possibility of
                      quantum criticality at very low temperatures.The magnetic
                      properties of CeCu2Ge2 were studied by magnetization
                      measurements and, usingthe strong magnetoelastic coupling,
                      by magnetostrictive investigations over a wide
                      temperaturerange and in fields up to 50 T. Especially, the
                      magnetostriction curves reveal clearly the detailsof the
                      temperature and field dependence of the phase transitions.
                      Here we present experimentalresults used for a refinement of
                      the H−T phase diagram in [100] and [110] direction.},
