Abstract
The mechanism of spin orientation under the interband tunnelling trans port of carriers due to the longitudinal current has been considered. The spin-dependent interband tunnelling probability has been calculate d for Kane and Dirac-like models. For lead chalcogenides and InAs/AlGa Sb/GaSb heterostructures the degree of spin orientation can be greater than 10% under weak current-induced longitudinal anisotropy of the di stribution function.
