## Title

- title: Interfacial Reactions and Spacer-Dependent Ordering in FePt–C/X–C/FePt–C
    (X = Ir, Pt, and Ag) Trilayer Nanostructures

## Description

- description: Spacer layers critically influence nanoscale interfacial reactions,
    strain transfer, and microstructural evolution in FePt based multilayer films.
    Here, FePt−C/X−C/FePt−C trilayer systems (X = Ir, Pt, Ag) are employed to examine
    how spacer material governs thermodynamic stability and interfacial chemistry.
    Distinct spacer-dependent behaviors are identified. Ir promotes strong wetting,
    which results in network-like FePt morphologies, Ag is immiscible with FePt, which
    leads to granular isolation but a loss of epitaxial continuity, and Pt undergoes
    interfacial interdiffusion, which forms an L12-ordered reaction phase at the spacer
    position.
