Single crystal growth and properties of Au- and Ge-substituted EuPd $_{2}$ Si $_{2}$

Michelle Ocker, Robert Möller, Marius Peters +7

We report on the single crystal growth of Eu(Pd $_{1 - x}$ Au $_{x}$ ) $_{2}$ Si $_{2}$ , $0 < x \leq 0.2$ , from a levitating Eu-rich melt using the Czochralski method. Our structural analysis of th…

Symmetric versus antisymmetric strain tuning of the valence transition in Yb(In $_{1 - x}$ Ag $_{x}$ )Cu $_{4}$

Caitlin I. O'Neil, Michelle Ocker, Kristin Kliemt +2

Similar to transitions in a range of correlated quantum materials, the valence transition exhibits a strong coupling to the crystal lattice, rendering it highly sensitive to stress…

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 $x \leq 0.23$ by the flux method. Through Co substitution, E…

Single crystal growth and physical characterization to fine tune YbIn1-xTxCu4 (T = Au, Ag) towards the critical endpoint of the valence transition

Michelle Ocker, Bereket Ghebretinsae, Jan-Niklas Zimmermann +6

Pure as well as Ag- and Au-substituted YbInCu $_{4}$ single crystals were structurally and chemically characterized and investigated by means of heat capacity, magnetization, resistiv…
