Abstract

Using quasielastic neutron scattering (QENS) and molecular dynamics (MD) simulations, dynamical disorder was shown to be present in the Zn6Sc cubic 1/1-approximant to Tsai type quasicrystals. This dynamical disorder originates from reorientations of the innermost tetrahedron shell inside the Tsai type clusters’ building blocks. To enable such a rotational motion inside a close-packed alloy, a unique dynamical flexibility is necessary. We present a study of the tetrahedron dynamics with respect to this structural flexibility.
