摘要

Bimetallic alloys with large discrepancies in atomic radii and crystal structure typically yield systems that are highly immiscible, even at high temperatures. The Ag_xFe_(1-x) binary system has limited solid and liquid solubility and thus phase separated Ag + Fe alloys should result. Furthermore, Ag has interesting plasmonic properties and Fe is a strong ferromagnet, thus magneto-plasmonic nanoparticles/films should result due to their phase separation. We have leveraged a combinatorial sputter deposition to synthesize thin films with a large Ag_xFe_(1-x) (0.19 ＜ x ＜ 0.84) phase space to correlate the composition and structure to the optical and magnetic properties for both as-deposited and annealed compositions.
