Abstract

We report the observation of metastable cubic phase with L1₂ superlattice in thin films of Cu₃Ge. It is shown that the equilibrium ordered phase with orthorhombic D0_a superlattice is formed directly from the L1₂ superlattice. If the atomic order is ignored, the transformation corresponds to the well-known face-centered cubic to hexagonal close-packed transformation.
