Cross-correlations between crystal field excitations and phonons in CeAl2
We would like to investigate inelastic neutron scattering spectra in CeAl2 in which strong coupling between a crystal-field excitation and phonons is realized. Using polarized neutrons, we want to solve discrepancy inelastic spectra between neutron and x-ray scattering, and search for nuclear-magnetic correlations. This study will deepen our understanding on spin-lattice coupling in f-electron systems and will be a first step toward the search of nuclear-magnetic mixed terms in CeAl2, a promising compound for this search due its the spin-phonon bound state.
