Magnetic excitations in the partially frustrated metal CePdAl
CePdAl is a unique intermetallic material, where both long-range magnetic order and magnetic frustration show up below the antiferromagnetic ordering temperature of 2.7K. Due to the arrangement of Ce ions on a distorted Kagomé lattice in the basal plane, geometric magnetic frustration is present. This results in a partially frustrated state, where only two thirds of the Ce ions participate in long-range magnetic order whereas the other third remains mainly disordered. The occurring interplay between Kondo physics and partial magnetic frustration in this metallic compound enables new investigations of strongly correlated effects, e.g. on quantum phase transitions, which occur at absolute zero temperature. In the proposed experiment, the magnetic excitation spectrum of CePdAl shall be studied. Especially excitations resulting from the frustrated Ce moments and their influence on the evolution of spin waves are of high interest to get a better understanding of the nature and stability of the partially frustrated state. Moreover, we want to look for anisotropic excitations by investigating the magnon dispersion along the magnetically hard and easy direction.
