Abstract

Summary form only given. A novel experimental set-up is presented to study the magnetoresistance of single and isolated ferromagnetic cobalt nanowires fabricated by electrodeposition into nanoporous membranes. In contrast to earlier studies, this method allows a multiprobe connection and thus to study the magnetoresistive response of different segments along the wire., Anglais

Abstract

Summary form only given. Electrodeposition of cobalt is a complex and rich problem. Several reports have shown that the wire diameter, deposition conditions, additives and temperature can give rise to very different structural and magnetic properties. We have studied the structural and magnetic properties of Co nanowires as a function of the electrolytic bath acidity. The structural properties have been studied by transmission electron microscopy (TEM) and the magnetic properties have been characterized by hysteresis loops and ferromagnetic resonance (FMR)., Anglais
