摘要：
A lateral spintronic device has been created on the basis of the InSb semiconductor with an iron injector and an iron detector of spin-polarized electrons that are separated from the semiconductor channel by a MgO tunnel barrier. The electric injection and detection of spin-polarized electrons in a single device have been demonstrated. Data on the parameters of the spin subsystem of conduction electrons in the InSb semiconductor and spin polarization of injected electrons in the semiconductor on the Fe/MgO/InSb heterojunction have been obtained from the measurements of the Hanle effect.
