Crystal-field excitations in CeB6 studied by Raman and neutron spectroscopy
Abstract
The 8-7 crystalline-electric-field (CEF) transition of CeB6 has been identified near 530 K (46 meV, 372 cm-1) with use of inelastic neutron and polarized Raman scattering. From the anomalous temperature behavior of the transition energy observed in Raman scattering we deduce a 8 ground state split by 20 cm-1 (30 K). The novel CEF level scheme yields a consistent and unified interpretation of so far seemingly unrelated thermal, elastic, and magnetic data. © 1984 The American Physical Society.
