Hall 4E/F (WSCC)
Many types of nanowires have been synthesized, with different techniques, to study basic science in low-dimensional systems and to use them on nanoelectronic devices. The synthesis of different types on nanostructures has been helpful in the understanding of the relation between superconductivity and ferromagnetism when they are placed in contact. Segmented superconductor-ferromagnetic (S/F) nanowires were successfully fabricated for this study. Policarbonate membranes with pores of 70 nm in diameter were used to deposit Sn and Cobalt through electrodeposition technique using positive voltages. The structure and morphology of the nanowires were studied using TEM. Electron diffraction pattern, of both segments, have shown that both metal grew single crystalline. The purpose of these devices is to describe the recently discovered phenomena on the proximity effect induced in a ferromagnet by a superconductor. Electrical transport measurements will be made to observe if this phenomenon survives between the boundaries of S/F nanowires. The results of PPMS will shed light on the role of the interface in the long-range proximity effect in ferromagnetic nanowires.
