Au/In bilayers studied with 111In deposited at the interface

Au/In bilayer samples of different stoichiometries were studied using the time-differential perturbed angular correlation technique. The ¹¹¹In probe atoms were deposited at the gold/indium interface to follow the formation of the intermetallic compounds at an early stage. Au-In phases of different composition (AuIn₂, AuIn, Au₇In₃, Au₃In) were created at the interfaces upon annealing. In addition a metastable Au₇In₃(m) phase, observed only after quenching in the bulk Au_0.7In_0.3 alloy, was found. This revised version was published online in August 2006 with corrections to the Cover Date.
