spinpolarisierte electron source using a multiple mikrospitzen existing emissionskathode, use in the physics of electron material or electron particle interactions in plasma physics, electron microscopy.

摘要

Spin polarized electron source using an emissive micropoint cathode. At least one portion of each micropoint, including the top of the latter, is ferromagnetic, so that the electrons emitted by the cathode are spin polarized in a given direction, when the portion is subject to a magnetic field parallel to the given direction.
