## Description

- description: Epitaxial thin films of fully nonequilibrium hcp-Ru_50Mo_50(0001) nanoalloys
    were prepared as a chemically disordered alloy, in which the intrinsic spin Hall
    effect is expected to be negligible. Structural analyses confirmed the epitaxial
    growth and atomic scale alloying of the films. In contrast to a tiny torque efficiency
    (ξ_DL) of ∼0.4% for Ru50Mo50/CoFeB, the ξ_DL for the Ru50Mo50/Ni heterostructure
    reached ∼30% with a long-range relaxation length. The apparent dependence of ξ_DL
    on the ferromagnetic layer can be attributed to the orbital Hall effect (OHE).
    Interestingly, a smaller ξ_DL was observed for Ru/Ni, suggesting that the nonequilibrium
    Ru_50Mo_50 enhances its OHE. Furthermore, the enhanced ξ_DL is maintained by inserting
    a Ru layer between the Ru_50Mo_50 and Ni layers, showing orbital transport through
    Ru. This finding illustrates potential applications of nonequilibrium nanoalloy
    films in spin orbitronics and contributes to getting insights into the understanding
    of the interrelationships between nanostructures and orbital transport properties.
