Crystal field parameters and g-factors of the ground Kramers doublet of Сe 3+ ion in LiYF 4 crystal

摘要

Analytical expressions are obtained for g-factors of the ground Kramers doublet of the impurity Ce 3+ ions in LiYF 4 crystal that rigorously take into account mixing of the 2 F 5/2 and 2 F 7/2 multiplets by crystal field. Dependence of g-factors on crystal field parameters is studied and possibilities of making conclusions about crystal filed parameters values on the basis of comparison with g-factors given in literature are considered.
