Abstract

In-plane lattice spacings of [Au(xÅ)/Ni(xÅ)] and [Pd(xÅ)/Cu(xÅ)] superlattice films with [111]fcc textures and large lattice misfits have been measured by X-ray diffraction. With decrease of superlattice period (Λ = 2x), Au and Pd layers are compressed whereas Ni and Cu layers are expanded. The observed lattice spacings (d220) of the individual layers vary almost linearly depending on 1/Λ. The lattice spacings of two constituent layers become equal in a Au/Ni superlattice with Λ = 8 A ̊ (d220 = 1.371 A ̊) and a Pd/Cu superlattice with Λ = 14 A ̊ (d220 = 1.337 A ̊).
