R. Parrot et al., HIGH-RESOLUTION STUDY OF THE MAGNETIC-FIELD EFFECT ON THE (4)E STATE OF MN2+ IN CUBIC ZNS BY LASER SPECTROSCOPY, Physical review. B, Condensed matter, 52(19), 1995, pp. 13983-13991
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.
