The conductivity and Hall effect of p-type doped Zn[sub (1-x)]Mn[sub x]Te 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. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR] |
