## Description

- description: Significant spin current generation from highly conductive materials
    is promising for spintronic applications, such as spin-orbit-torque magnetic random-access
    memories. In this work, we fabricated epitaxial Ru/Cu heterostructures with interface
    engineering where 1-nm-thick Ru and Cu layers were alternately deposited at the
    interface. The spin current generation in the heterostructures was evaluated by
    unidirectional spin Hall magnetoresistance and spin-torque ferromagnetic resonance.
    A sizable spin Hall efficiency (~-2%) was achieved in the Ru/Cu sample with a
    sharp interface which may result from the interface spin filtering effect. Increased
    spin Hall efficiency (~-4%) was observed in the interface-engineered samples which
    could be attributed to the intrinsic contribution from lattice distortion and
    local band structure near the interface. The effective spin Hall conductivity
    was estimated to be comparable to that of Platinum.
