Critical behavior and evidence of dimensional crossover in quasi-two-dimensional Li $_{2}$ FeSiO $_{4}$

Waldemar Hergett, Kevin Ackermann, Erik Walendy +5

We report thermal expansion and heat capacity studies on Li $_{2}$ FeSiO $_{4}$ single crystals which enable us to investigate the critical behavior in the magnetically quasi-two-dimensio…

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…
