A study of magnetotransport in the n-Si/SiO_2/Ni nanostructures with granular Ni nanorods in SiO_2 pores was performed over the temperature range 2-300 K and at the magnetic fields induction up to 8 T. The n-Si/SiO_2/Ni Schottky nanostructures display the enhanced magnetoresistive effect at 25 K due to the impurity avalanche mechanism.
