Two stage pressure-induced Yb valence change in the Hexagonal Laves Phase YbAg${}_2$: Investigation by time differential perturbed angular $\gamma$-$\gamma$ correlation spectroscopy method and density functional calculations

A. V. Tsvyashchenko, A. N. Nikolaev, D. A. Salamatin +8

We have studied the C14 hexagonal Laves phase of YbAg${}_2$ at normal conditions and under external pressure up to 19 GPa by the time-differential perturbed angular $\gamma -\gamma$ correlation…
