Title

Magnetoelastic coupling of crystal field transitions and lattice excitations in CePdAl3

Abstract

A new kind of magnetoelastic coupling was observed in the tetragonal compounds of the CeTAl3 family of compounds. The coupling involves the localised transition between the crystal electric field split levels of the magnetic Ce ion and the phonons, collective vibrations of the lattice atoms. On the other hand we have observed that in CeTAl3 compounds the magnetic ordering is strongly influenced by the lattice symmetry. This motivated us to investigate the interaction between the crystal field transitions and phonons in the orthorhombic CePdAl3. We want to determine the crystal field energy levels and look for hints for phonon-crystal field coupling in broad Q-range.
