Magnetic structure study in CeCuAl3 single crystal
CeCuAl3 crystallizes in the tetragonal BaNiSn3-type structure (space group I4mm, 107) and orders antiferromagnetically with Néel temperature 2.6 K. CeCuAl3 shows interesting magnetic behavior which is generally discussed as a result of interplay between the magnetic RKKY and Kondo interactions and the influence of the low lying excited CEF state. It is among a few cerium compounds where the strong magneto-elastic coupling resulting in new quasi-bound states, vibrons, was found. Despite numerous bulk studies, the unambiguous microscopic evidence of the magnetic ground state nature is still missing. Our previous test experiment on CYCLOPS and recent inelastic neutron scattering experiment (PANDA, MLZ) revealed the propagation vector (0.6, 0.4, 0) in CeCuAl3. The aim of proposed experiment is to determine all the details of the magnetic structure. The measurement will be performed on the same single crystal as all previous neutron scattering experiments.
