The study of the carrier transport and magnetotransport in n-Si/SiO2/Ni nanostructures with granular Ni nanorods embedded into the pores in SiO2 was performed over the temperature range 2 – 300 K and at the magnetic field induction up to 8 T. In n-Si/SiO2/Ni nanostructures at temperatures of about 25 K a huge positive MR effect is observed. Possible mechanisms of the effect is discussed.

Przeprowadzono badania mechanizmu przenoszenia ładunków i magnetoprzewodzenia w nanostrukturach n-Si/SiO2/Ni z ziarnistymi nanocząstkami Ni rozmieszczonymi w porach SiO2 w zakresie temperatur 2 - 300 K oraz przy indukcji magnetycznej do 8 T. W nanostrukturach n-Si/SiO2/Ni w temperaturze około 25 K zaobserwowano bardzo wyraźny dodatni efekt MR. Omówiono prawdopodobne mechanizmy pojawienia się opisanego efektu.
