Özet

The article reports the development of new type of magnetic tip to manipulate magnetic nanowires. The amorphous ferromagnetic tip has a composition of Fe77.5Si7.5B15. Electrochemical etching was performed at room temperature for various dc currents up to 5 mA. It was found that 4.4 mA etching current was the best tip formation current for the FeSiB wire. It was found that the tip radius is smaller than 200 nm after the etching process. Magnetic NiFe nanowires were manipulated using a 3D positioning system with the FeSiB tip. (C) 2015 Elsevier B.V.
