- 論文の詳細を見る
Unique structural evolution was observed in the suitably designed nanosized Pd-Ru multilayers by a scheme named ion beam manipulation, i.e., ion beam mixing in a controllable manner. With increasing the ion dose, the original polycrystalline Pd and Ru first transformed into an intermediate state of single crystalline fcc phase, which later turned into a well-grown ordered structure. When the multilayers were over-irradiated, the ordered structure showed an apparent tendency of returning to a polycrystalline state of fcc Pd-enriched solid solution. We report, in this Letter, experimental observations as well as a brief discussion concerning the roles of interfacial free energy and irradiation dose in manipulating the structural evolution observed in the Pd-Ru multilayers.
