Magnetic properties of CoCu nanowires in self-assembled arrays

Extra application of magnetic nanowires and the importance of GMR phenomenon in magnet/non magnet nanowires attracted our interests to investigate the effects of pulse electrodeposition on magnetization decrease in alloy nanowires of CoCu in different copper concentration to achieve the optimum conditions to fabricate multilayer nanowires. In addition saturation magnetization and coercivity field of alloy CoCu nanowires embedded in porous alumina template and the effect of annealing on magnetic properties were studied. Firstly ordered nanopores were fabricated by two step mild anodization and then nanowires were grown inside them by pulse and ac electrodeposition methods. Also the effects of electrodeposition and copper concentration on nanowires behavior were studied by scanning microscope(SPM)&(SEM) alternating gradient force magnetometer (AGFM) x-ray diffraction pattern (XRD)and EDS analysis.
