Objective
Deep X-ray lithography (in Novosibirsk) will be used to pattern resist layers deposited on Cu and other strates in order to create templates suitable for the electrodeposition of metal wires with lengths of several um and diameters of less than 1 µm. CoCu alloy/Cu and CoNiCu alloy/Cu multilayer nanowires will be electrodeposited in these templates (in Novosibirsk, Lausanne and Bristol) from a number of electrolytes (sulphate, sulphamate and acetate) under potentiostatic control, and used in studies of current perpendicular to plane giant magnetoresistance (CPP GMR). Their morphology, composition and structure will be determined by scanning electron microscopy, Xray microanalysis and Xray diffraction (XRD), and the results correlated with the CPP GMR measurements. The ability to choose the strate for nanowire deposition and thereby control the crystallographic orientation of the nanowires is a major advantage of using templates fabricated by Xray lithography in place of the commercial track etched polycarbonate membranes used in previous nanowire experiments. Electrochemical procedures will be developed (in Minsk) to allow the deposition of multilayer nanowires in which the nonmagnetic layer is Ag, and CPP GMR results for CoAg alloy/Ag and CoNiAg alloy/Ag nanowires will be compared with results for sputtered Co/Ag multilayers as well as for other electrodeposited nanowires. Low temperature remanence measurements will be carried out (in Lausanne) to study interactions between the magnetic layers in multilayer nanowires. The interaction strength will be varied by varying the wire diameter and the thicknesses of the magnetic and nonmagnetic layers. Single component Co, Ni and CoNi alloy nanowires will also be studied in order to establish the mechanism for magnetization reversal in an applied field. The use of lithographically fabricated templates will simplify data analysis compared to previous experiments because all the nanowires will be parallel. Our results should contribute to a greater understanding of the properties of arrays of magnetic particles, which are not only of interest in themselves, but are also relevant to the magnetic recording industry, for example.
