“…Even though the existence of AF coupling across the Pt spacer had been predicted theoretically [4], extensive studies on [Co/Pt] n multilayers with perpendicular anisotropy had just revealed the FM interlayer coupling [5][6][7]. Our recent investigations on the Co(4Å)/Pt(t PtÅ )/[Co(4Å)/Pt(6Å)] n multilayers with spin-valve configuration had reported the AF interlayer coupling through the Pt spacers [8][9][10][11][12]. The IEC oscillates as a function of Pt spacer thickness and repetition number at AF coupling background.…”

“…Fe, Ni, Co or their alloys and a non-magnetic transition or noble metal, e.g. Ag, Cu, Pt etc., because they can exhibit special properties such as the magneto-optic Kerr effect, anisotropic magnetoresistance (AMR) and giant magnetoresistance (GMR) [2][3][4][5][6][7][8][9]. The effect of GMR in Fe/Cr multilayers is much stronger than the usual AMR, measured for a single Fe layer with the same thickness, which was prepared in similar growth conditions in order to enable comparison.…”

In this work, we grow composite structures consisting of magnetic and non-magnetic metal or alloy nanowires electrodeposited into the ion etched tracks previously created inside Si substrates. The holes are then filled by Co-Pt alloys and Co/Pt multilayers using electrodeposition technique making a large number of parallel nanowires. This process takes place in a single electrolyte containing Co þ2 and Pt þ4 ions by applying a proper deposition potential using a computer control potentiostat. The magnetic properties of the sample were studied using vibrating sample magnetometer. Magnetoresistive behaviour of the nanowire samples was then studied by subjecting the samples to an external magnetic field. The results show that the Co/Pt multilayered nanowires exhibit a large magnetoresistance, while the Co-Pt alloys only show anisotropic magnetoresistance. This result could be of a great interest for the sensor fabrication community as they will provide a view on a very important direction of the development of the wide spread sensor industry, and more importantly for understanding the physical phenomena underlying the magnetic/non-magnetic nanostructures.
