GROUP-CHAIN SCHEME ANALYSIS OF THE ENERGY LEVELS AND MAGNETIC PROPERTIES OF Nd 3+ IN LiYF 4 CRYSTAL
Based on the analysis of group-chain scheme, the crystal-field-level fitting of Nd3+:LiYF4 has been carried out, in which the Nd3+ ions occupy positions with site symmetry S4. The RMS deviation of energy-level fitting is 12.8 cm-1. Using the obtained wave functions, g-factors of the ground state are calculated, which are g||?=?2.067 and g??=?2.631, in good agreement with the experimental values (g|| = 1.987 and g??=?2.554). The method proposed turns out to be effective in the study of spectral properties of localized centres in laser crystals.
