Description

A lattice-stiffening transition is observed near 230 K in corrugated 'chain like' gadolinium structures formed on Mo(112) and W(112). This transition is evident from the change in the effective Debye temperature. Below the transition temperature of 230 K the gadolinium overlayer lattice has much higher effective Debye temperature than that observed for higher temperatures (for the quasi-one-dimensional Gd sub-monolayer structures or for the higher coverage overlayers). From model studies, lateral dipole-dipole and indirect interactions as well as the interaction between the adatoms and the substrate play an important role in this transition
