The scientists synthesized multi-layered copper and nickel nanowires in order to study their characteristics, which depend on the layers' composition and geometry. "We expect that the transition to multi-layered nanowires will increase this magnetoresistance effect considerably. Today, we are choosing the method of nanowire synthesis in order to get this effect," said co-author Ilia Doludenko of the Moscow Institute of Electronics and Mathematics (MIEM HSE).

To determine the correlation between the synthesis parameters and the crystal structure, the scholars synthesized nanowires of different lengths. The nanowire length was determined by the number of deposition cycles; one nickel layer and one copper layer were deposited in each cycle. The size of the nanowires was determined using a scanning electron microscope (SEM). The number of pairs of layers in the nanowires was found to be 10, 20, or 50, according to the number of electrodeposition cycles.
