Strongly Entangled Kondo and Kagome Lattices and the Emergent Magnetic Ground State in Heavy-Fermion Kagome Metal YbV $_{6}$ Sn $_{6}$

Rui Lou, Max Mende, Riccardo Vocaturo +31

Applying angle-resolved photoemission spectroscopy and density functional theory calculations, we present compelling spectroscopic evidence demonstrating the intertwining and mutua…

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…

Magnetic Phase Diagram of YbRh\textsubscript{2}Si\textsubscript{2}: the Influence of Hyperfine Interactions

Jan Knapp, Lev V. Levitin, Jan Nyeki +6

We report the determination of the magnetic phase diagram of the heavy fermion metal YbRh\textsubscript{2}Si\textsubscript{2} in magnetic fields up to 70\,mT applied perpendicular…

Electron Spin Resonance of Eu on triangular layers in EuT2P2 (T =Mn, Zn, Cd)

JÃ¶rg Sichelschmidt, Pierre Chailloleau, Sarah Krebber +3

We report on the electron spin resonance (ESR) of Eu $^{2 +}$ in Eu $T_{2}$ P $_{2}$ ( $T$ =Mn, Zn, Cd) single crystals. The temperature dependencies of ESR linewidth and resonance shift…

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…

Robust Magnetic Polaron Percolation in the Antiferromagnetic CMR System EuCd $_{2}$ P $_{2}$

Marvin Kopp, Charu Garg, Sarah Krebber +16

Antiferromagnetic EuCd $_{2}$ P $_{2}$ has attracted considerable attention due to its unconventional (magneto)transport properties. At a temperature $T_{peak}$ significantly above th…
