Crystal field excitations in YbT{sub 2}Si{sub 2} (T = Fe, Co, Ni)

Crystal field excitations in YbT{sub 2}Si{sub 2} (T = Fe, Co, Ni)

The results of an inelastic neutron scattering investigation of the crystal field potential of YbT{sub 2}Si{sub 2} (T = Ni, Co, Fe) are reported. We have observed well-defined inelastic peaks due to crystal field transitions for all three compounds. By performing a profile refinement of the measured...

Zusammenfassung:The results of an inelastic neutron scattering investigation of the crystal field potential of YbT{sub 2}Si{sub 2} (T = Ni, Co, Fe) are reported. We have observed well-defined inelastic peaks due to crystal field transitions for all three compounds. By performing a profile refinement of the measured spectra, we have determined the parameters of the crystal field Hamiltonian for YbCo{sub 2}Si{sub 2} and YbNi{sub 2}Si{sub 2}.
