## Description

- description: "This paper examines the phonon dispersion and static local atomic
    distortion of iron-manganese-based Elinvar alloys using high-resolution inelastic
    X-ray scattering, magnetization, neutron diffraction, and neutron total scattering.
    In this study, nonlinear phonon dispersion was observed for a transverse acoustic
    mode near zone center, associated with (\U0001D43611−\U0001D43612)/2 elastic constants,
    over a wide temperature range along the \U0001D6E4⁡(220) to X (310) points of
    the face-centered cubic system, indicating lattice instability coupled with tetragonal
    distortions in the long-wavelength limit. Bulk magnetization and neutron diffraction
    measurements suggest that the conventional ferromagnetic magnetostriction scenario
    is not the origin of Elinvar characteristics. Instead, the martensitic transformation
    and lattice instabilities underlie these phenomena. The reduced pair distribution
    function reveals a significant discrepancy between local and global (averaged)
    structures suggesting the influence of atomic-scale lattice disorder and instability
    in FeMn-based Elinvar alloys."
