抄録

Effects of spin-orbit (SO) coupling and the s-d exchange interaction are probed by magnetoresistance (MR) measurements in ZnO and (Zn,Mn)O. A quantitative description of the data for ZnO in terms of weak localization (WL) theory makes it possible to determine the SO coupling constant λso, = (4.4 ± 0.4) × 10-11 eVcm. A complex and large positive MR of (Zn,Mn)O is interpreted as an effect of the s-d spin-splitting on the disorder-modified electron-electron (e-e) interactions. A large negative MR is tentatively assigned to a precursor effect of the magnetic polaron formation.
