Influence of the preparation method on the properties of Cu–Co heterogeneous alloys

Abstract Cu88Co12 samples have been obtained by electrodeposition and laser ablation and have been annealed at increasing temperatures (450°C, 500°C and 550°C) to compare the influence of the fabrication method on the magnetotransport properties of the samples. Magnetoresistance (MR) and X-ray diffraction (XRD) measurements show different properties between the samples prepared by the two techniques. It was found that the electrodeposited (ED) samples had a larger MR. The properties of the laser-ablated samples depend on the deposition process, showing an anisotropy when prepared with a smaller target rotation speed.
