Towards a critical endpoint in the valence fluctuating Eu(Rh${}_{1-x}$Co${}_x$)${}_2$Si${}_2$ system

Franziska Walther, Michelle Ocker, Alexej Kraiker +4

We report on the successful single crystal growth of pure EuRh${}_2$Si${}_2$ and of Eu(Rh${}_{1-x}$Co${}_x$)${}_2$Si${}_2$ with $x\le 0.23$ by the flux method. Through Co substitution, E…
