The metallic heavy-fermion compound CePdAl might be a model system to investigate the influence of magnetic frustration on quantum criticality. The antiferromagnetic order below 2.7K can be suppressed by applying hydrostatic or chemical pressure. Due to the arrangement of Ce ions on a distorted Kagomé lattice in the basal plane, geometric magnetic frustration is present. Neutron scattering experiments reveal, that only two third of the Ce ions participate in long-range magnetic order whereas the other third remains mainly disordered. Recently we detected in addition to the long-range ordered magnetic peaks weak and broad magnetic signals at “forbidden” positions due to the geometric frustration of the Ce moments. These short-range ordered peaks have not been seen before and shall now be studied in this experiment to find out, how magnetic frustration influences the magnetic order of CePdAl. Thereby magnetic fields shall be applied along the basal plane to change the frustration.
