摘要：
The conductivity and Hall effect of p-type doped Zn(1-x)MnxTe layers are described and analyzed in terms of a two-fluid model where part of the carriers are weakly localized as bound magnetic polarons. At low temperature, the Hall effect is dominated by the spin-dependent component (extraordinary Hall effect), in good agreement with a crude estimate taking into account the properties of the valence band. The long range ferromagnetic interaction appears to be induced by the weakly localized holes. (C) 2000 American Institute of Physics. [S0021-8979(00)82408-1].
