Abstract of Publication No. 393
Inelastic neutron scattering (INS) measurements were performed on the rare
earth dimer compound Cs3Er2Br9. The crystalline electric
field (CEF) parameters were determined. The lack of any exchange splitting
associated with the CEF transitions can be explained by the lare single
ion anisotropy for Er. An energy level scheme is proposed, which was tested
with extensive magnetization and specific heat measurements as a function
of temperature and magnetic field.
