Clamping effect on temperature-induced valence transition in epitaxial EuPd${}_2$Si${}_2$ thin films grown on MgO(001)

Sebastian Kölsch, Alfons Schuck, Olena Fedchenko +10

Bulk EuPd${}_2$Si${}_2$ show a temperature-driven valence transisition of europium from $\sim$+2 above 200 K to $\sim$+3 below 100 K, which is correlated with a shrinking by approximat…
