摘要
We present millikelvin studies of diffusive charge transport in submicron wires of n(+)-CdTe and n(+)-Cd0.99Mn0.01Te epilayers. In contrast to expectations, the paramagnetic Mn impurities leave a mean amplitude of reproducible magnetoconductance fluctuations unchanged but decrease the fluctuation correlation field. These findings are interpreted by invoking a new driving mechanism of the magnetoconductance fluctuations-the redistribution of the electrons between energy levels of the system, induced by the giant s-d exchange spin splitting.
