Abstract
Weak-field magnetoresistance and universal conductance fluctuations ha ve been studied at millikelvin temperatures in submicron wires of In-d oped n(+)-CdTe and n(+)-Cd0.99Mn0.01Te. The fluctuations contain a per iodic component of unknown origin. The giant spin-splitting of the ele ctron states, caused by the s-d exchange interaction with the Mn spins , results in the positive magnetoresistance and the temperature depend ence of the fluctuation pattern.
