在ZnSe：Mn和ZnSe：Fe晶体中观察到1s激子反射谱的巨大磁场分裂。这种效应归因于进入自由激子的载流子与磁性杂质离子之间的交换作用。这些效应在定性和定量上都与早先报道的对ZnTe：Mn和CdTe：Mn的影响相似。C带电子与杂质3d离子的交换作用是铁磁性的，而v带电子是反铁磁性的。所研究的磁掺杂晶体中激子内电子-空穴交换相互作用的数值与未掺杂的ZnSe晶体中的数值不同。讨论了ZnSe：Mn和ZnSe：Fe效应的特点。

Gigantic magnetofield splitting of the 1s exciton reflection spectrum is observed in ZnSe:Mn and ZnSe: Fe crystals. The effects are attributed to the exchange interaction between the carriers which enter in the free exciton and the magnetic impurity ions. The effects are qualitatively and quantitatively similar to the earlier one reported for ZnTe:Mn and CdTe:Mn. The exchange interaction of the c-band electron with impurity 3d ions is ferromagnetic while for the v-band electron it is antiferromagnetic. The values of intraexciton electron-hole exchange interaction in magnetodoped crystals under investigation are found to be different from the reported'ones in nondopedc ZnSe crystals. The peculiarities of the effects in ZnSe:Mn and ZnSe:Fe are discussed.
