CePdAl is a geometrically frustrated heavy fermion compund that orders antiferromgnetically below TN = 2.7 K with an incommensurate structure with Q = (0.5 0 0.35)and is in the vicinity to a quantum cristical point (QCP). Only 2/3 of the Ce moments show long-range-order below TN, while the remaining 1/3 shows only short-range-ordering which is directly connected to the frustration in the system. While TN can be changed by pressure or concentration tuning, frustration is supposed to span a new axis in the parameterspace in tuning a QCP. We propose to study the influence of geometrical frustration on the magnetic order and TN in CePdAl. Therefore we want to apply uniaxial pressure along the ab-plane in order to decrease the symmetry of the Ce-triangles and therby lift the frustration.
