The present research deals with the swift heavy ion track technology, which includes irradiation of a material by Au ions (energy 350 MeV, fluence 108 cm−2), chemical etching of resulting swift heavy ion tracks and precision electrochemical deposition of magnetic metals in the resulting nanopores.
In this way structures on the base of SiO2/n-Si with nanopores in silicon dioxide layers, filled with Ni nanoclusters, have been prepared and studied. Investigations of current-voltage dependences and magnetic characteristics of the obtained structures with Ni nanoclusters at strong magnetic fields up to 8 T and at low temperatures in the range of 1.8 K - 150 K have shown a possibility of control of these nanostructures properties by the effect of magnetic fields.
The obtained results confirm a feasibility of the use of the Si/SiO2/Ni nanoelectronic systems with swift heavy ion tracks in low-temperature spintronic sensor devices.
