## Description

- description: Spin current is a flow of spin angular momentum and is considered as
    an ideal information carrier for spintronic devices due to the merit of low power
    consumption. However, an efficient conversion between charge and spin current
    usually depends on the strong spin-orbit interaction (SOI) in heavy 5d metals
    such as Pt and Ta. Here we report a remarkable enhancement in the spin transport
    property in a negligible SOI system of Cu50Ru50. Although Cu-Ru system is bulk-immiscible,
    the Cu50Ru50 film, prepared by the alternate monoatomic layer deposition method,
    is a nano artificial alloy and the atomic-scale intermixing has been directly
    confirmed by atomic-resolution energy-dispersive X-ray spectroscopy. Compared
    with pure Cu and Ru metals, we find 100 times enhancement in unidirectional spin
    Hall magnetoresistance detected in this nano artificial alloy, which is comparable
    to values in Pt and Ta. Our findings are expected to be applicable to other bulk-immiscible
    metallic systems with a weak SOI, which paves a way for designing novel alloy
    films with desirable properties and functionalities.
