In this work anisotropic magnetoresistance in nanogranular Ni lms and Ni nanorods on Si(100) wafer substrates was studied in wide ranges of temperature and magnetic eld. To produce Ni lms and nanorods we used electrochemical deposition of Ni clusters either directly on the Si substrate or into pores in SiO2 layer on the Si substrate. To produce mesopores in SiO2 layer, SiO2/Si template was irradiated by a scanned beam of swift heavy 350 MeV 197 Au 26+ ions with a uence of 5 × 10 8 cm −2 and then chemically etched in diluted hydrouoric acid. Pores, randomly distributed in the template have diameters of 100250 nm and heights about 400500 nm. Comparison of temperature dependences of resistance and magnetoresistance in Ni lms and n-Si/SiO2/Ni structures with Ni nanorods showed that they are strongly dependent on orientation of magnetic eld and current vectors relative to each other and the plane of Si substrate. Moreover, magnetoresistance values in n-Si/SiO2/Ni nanostructures can be controlled not only by electric eld applied along Si substrate but also by additionally applied transversal bias voltage.
