Influence of the Thickness of Nonmagnetic Spacer on the Magnetic Properties of Fe/Cu Multilayered Nanowires

Abstract:

We present a systematic investigation on the equilibrium structure, stability and magnetic properties of one-dimensional Fe/Cu multilayered nanowires with different width of nonmagnetic Cu spacer using first-principles calculations. The multilayered nanowires preserve their FCC (001) directional lattice symmetry after structural optimization. It is found that the stability of Fe/Cu multilayered nanowires decreases with increasing concentration of nonmagnetic Cu layers. The calculated interlayer exchange coupling (IEC) is found to switch signs as the thickness of nonmagnetic Cu spacer increases in the nanowire, and the magnitude of the IEC value is found to decrease significantly with increasing the number of nonmagnetic Cu layers.
