Magnetotransport of arrays of hybrid magnetic nanowires grown in porous alumina templates — •Sergej Andreev, Julian Braun, and Torsten Pietsch — Department of Physics, University of Konstanz, Universitätsstraße 10, 78464 Konstanz, Germany

Highly ordered hexagonal arrays of metallic and semiconducting nanowires recently attracted considerable interrest due to potential applications in energy storage and -conversion as well as catalysis and communication technologies. Porous alumina templates have been widely used to fabricate such nanowires with diameters in the range of 50 nm to hundreds of nanometers. Here, we investigate novel types of hetero-nanowires fabricated via deposition of different metals into porous alumina templates. The nanowires with diameters down to 20 nm are prepared via co-electrodeposition of different magnetic metals. We show that micrometer sized arrays of nanowires can be integrated into lithographically designed circuits and we investigate the (magneto)-transport properties of magnetic hetero-nanowires at low temperatures.
