## Description

- description: Although the relationship between magnetostriction and magnetic damping
    is often described phenomenologically, their intrinsic connection remains unclear.
    In this Letter, we demonstrate that the magnitude of magnetic damping depends
    on the sign of magnetostriction in (Fe_{1−x}Co_{x})_{4}N and Ni _{1−y}Co_{y} alloys
    across various compositions, consistent with experimental observations. This behavior
    is attributed to strain-induced changes in exchange splitting, which shift the
    minority-spin density of states near the Fermi level, thereby affecting both magnetostriction
    and damping through spin-conserving transitions. Additionally, the presence of
    locally degenerate orbitals plays a crucial role in determining magnetostriction.
    These findings suggest that magnetization dynamics and magnetostriction can be
    intrinsically controlled, facilitating the design of magnetic materials for applications
    such as flexible spintronics.
