説明:

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.
