Crystalline electric field as a probe for long-range antiferromagnetic order and superconducting state of CeFeAsO(1-x)F(x)

We use inelastic neutron scattering to study the crystalline electric field (CEF) excitations of Ce3+ in CeFeAsO(1-x)F(x) (x=0, 0.16). For nonsuperconducting CeFeAsO, the Ce CEF levels have three magnetic doublets in the paramagnetic state, but these doublets split into six singlets when the Fe ions...
