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

Abstract

We report on infrared to visible Zeeman absorption spectroscopy and parametrised crystal-field modelling of Nd3+ centres in Y2SiO5 through the use of experimentally inferred crystal-field energy levels and Zeeman directional electronic g values. We demonstrate that good agreement between the calculated and experimental crystal-field energy levels as well as directional Zeeman g values 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 the 2H11/2(2) multiplet in a one-electron crystal field model.
