• The energy gap (E_g) and the Verdet constant were examined for quaternary Cd_<0.55-y>Hg_yMn_<0.45>Te thin films with y≦0.11. As the Hg content increases, the E_g decreases and the S-shaped dispersion of the Verdet constant spectrum shifts to a lower photon energy. The magnitude of the Verdet constant for the film with E_g=1.78 eV (y=0.11) is about 1.9 times larger than that for the Cd_<0.8>Mn_<0.2>Te film with E_g=1.78 eV. It is thought that the large Faraday effect of the Cd_<0.55-y>Hg_yMn_<:0.45>Te films in the lower-photon-energy region is based on the large Zeeman splitting enhanced by Mn^<2+>, as in the case of ternary Cd_<1-x>Mn_xTe.
