Abstract

The biaxial elastic constants and viscosity between 100 and 300 °C of amorphous PdSi/PdSiFe multilayered thin films with repeat lengths between 2.0 and 4.9 nm have been determined using substrate curvature measurements. No dependence on repeat length has been seen for either property. Linear increases of the multilayer viscosities with time are observed. An analysis of the viscous flow of multilayers shows that in the present case this regime is reached after a very short transient period.
