Source of spin polarized electrons using an emissive micropoint cathode |
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.
