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…
