Crystal field excitations in rattling clathrate CeBa${}_7$Au${}_6$Si${}_{40}$

Michelangelo Tagliavini, Federico Mazza, Xinlin Yan +6

We investigate the local crystal-field environment of cerium in the clathrate compound CeBa${}_7$Au${}_6$Si${}_{40}$ (Ce-BAS) using resonant inelastic x-ray scattering (RIXS) and magneti…
