摘要：

It is shown that in ballistic quasi two-dimensional electron systems momentum jumps of spin-polarized electrons appear whenever an increasing in-plane magnetic field depopulates magnetoelectric sub-bands at low temperatures. The system acts as a polarized beam splitter, the filtered spin-polarized electrons being spatially separated from the mainstream electron current. The momentum jumps can be also used to implement quantum logic states or electron switches. (c) 2005 Elsevier B.V. All rights reserved.
