N2 - The role of spin-orbit and s-d exchange interactions is investigated by magnetoresistance (MR) measurements carried out down to 50 mK on ZnO and Zn 1-xMn xO with x = 3 and 7% and electron concentration ∼ 10 20 cm -3. The data for ZnO:Al leads to the coupling constant λ so = (4.4 ± 0.4) × 10 -11 eV cm of the kp hamiltonian for the wurzite structure, H so = λ soc(s × k). Complex MR of Zn 1-xMn xO:Al is interpreted in terms of the influence of the s-d spin-splitting on the disorder-modified electron-electron interactions and precursor effects of magnetism-related localization.
