Abstract (en)

[origin: DE19746138A1] The polarisation direction detection method detects the electrical field resulting from the magnetic deflection of the spin polarised electrons as a voltage, the electron injection effected by application of a voltage between a ferromagnetic contact body (2) and a non-ferromagnetic contact body (3) applied to the surface of a silicon body (1). The electrical field may be measured as a voltage obtained across 2 further contacts (4,5) positioned transverse to the mean flow direction (6) of the electrons (8).
