Zeeman spectroscopy and crystal-field analysis of low symmetry centres in Nd3+ doped Y2SiO5

We report on infrared to visible Zeeman absorption spectroscopy and parameterised crystal-field modelling of Nd3+centres in Y2SiO5through the use of experimentally inferred crystal-field energy levels and Zeeman directional electronicgvalues. We demonstrate that good agreement between the calculated and experimental crystal-field energy levels as well as directional Zeemangvalues along all three crystallographic axes can be obtained. Further, we demonstrate that the addition of correlation crystal field effects successfully account for discrepancies that arise between the calculated and experimental values relevant to the2H11/2(2) multiplet in a one-electron crystal field model.
