Abstract
The influence of a magnetic field on the fine-structure lines of the ( 4)E State of Mn2+ in pure cubic ZnS has been studied up to 5 T by usin g polarization-modulated laser spectroscopy. Very detailed analyses of polarized excitation spectra of the transitions (6)A(1) --> (4)E show that all authorized transitions have been observed between the Zeeman sublevels of the Kramers doublets Gamma(6) ((4)E), Gamma(7) ((4)E), a nd spin quartet Gamma(8) ((4)E) and the levels (6)A(1) (M(S) = -5/2) a nd (6)A(1) (M(S) = -3/2) of the fundamental state. Many other transiti ons from the levels (6)A(1) (M(S) = -1/2), (6)A(1) (M(S) = +1/2), and (6)A(1) (M(S) = +5/2) have been observed at low magnetic field. It is shown that the Zeeman effect on the levels Gamma(6), Gamma(7), and Gam ma(8) is correctly described by the Zeeman Hamiltonian g(e) mu(B)H . S , and that the contribution of the term in mu(B)L . H, which appears i n second-order perturbation schemes involving the spin-orbit interacti on, is negligible.
