Résumé

Ballistic hot electrons are extracted from a magnetic tunnel junction and injected into a metallic base with energies ranging from 0.65 to 2.8 eV. The energy and wave vector analysis made by a low height Si/Cu Schottky barrier allows one to disentangle the different contributions to the scattering. The hot electrons transport is interpreted as being mainly influenced by inelastic scattering. An explicit transport model reproduces our measurements and explains them as resulting directly from an electron-electron inelastic scattering process related to the sp and d bands of the ferromagnetic material involved.
