摘要：

The indirect exchange is treated for magnetic moments located in a thin semiconductor layer which is imbedded in the corresponding nonmagnetic quantum well host. The interaction is mediated by carriers provided by remote doping. The specific case of Cd1-xMnxTe is considered. A significant Curie-Weiss temperature is obtained for several possible arrangements of the magnetic layer and the quantum well widths, and the carrier (hole) density. We found a substantial contribution of virtual transitions involving continuum states for high enough carrier density. (C) 1999 American Institute of Physics. [S0021-8979(99)29808-8].
