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 single crystals were structurally and chemically characterized and investigated by means of heat capacity, magnetization, resistiv…
Magneto-acoustic study near the quantum critical point of the frustrated quantum antiferromagnet Cs2CuCl4
P. T. Cong, L. Postulka, B. Wolf +5
Magneto-acoustic investigations of the frustrated triangular-lattice antiferromagnet Cs2CuCl4 were performed for the longitudinal modes c11 and c33 in magnetic fields along the a-a…
Elastic constants and ultrasound attenuation in the spin-liquid phase of CsCuCl
S. Streib, P. Kopietz, P. T. Cong +5
The spin excitations in the spin-liquid phase of the anisotropic triangular lattice quantum antiferromagnet CsCuCl have been shown to propagate dominantly along the crystal…
Critical Phenomena at the Antiferromagnetic Phase Transition of Azurite
P. T. Cong, B. Wolf, R. S. Manna +3
We report on high-resolution acoustic, specific-heat and thermal expansion measurements in the vicinity of the antiferromagnetic phase transition at T_N = 1.88 K on a high-quality…
Effects of Two Energy Scales in Weakly Dimerized Antiferromagnetic Quantum Spin Chains
A. Brühl, B. Wolf, V. Pashchenko +9
By means of thermal expansion and specific heat measurements on the high-pressure phase of (VO)PO, the effects of two energy scales of the weakly dimerized antiferromag…
