Abstract
The optical absorption spectra of single crystal TmCl3·6H2O and Tm3+ in YCl3·6H2O have been investigated between 2500 and 8000 Å at 4.2 and 77°K. The spectra were studied as a function of magnetic field strength and as a function of crystal orientation relative to the magnetic field. Both optical and EPR data indicate a nearly accidental degeneracy in the ground state of tripositive thulium in the hydrated chloride salts. The magnetic moment is found to be perpendicular to the twofold axis of symmetry and the zero field splitting is found to be 1.12 cm−1. The observed splitting factor is 14.00 ± 0.05 LU.Keywords
