Reply to the Comment by S. Wirth et al. on "Tuning low-energy scales in YbRh$_2$Si$_2$ by non-isoelectronic substitution and pressure"
M.-H. Schubert,Y. Tokiwa,S.-H. Hübner,M. Mchalwat,E. Blumenröther,Hirale S. Jeevan,Philipp Gegenwart +6 more
TL;DR: Schubert et al. as mentioned in this paper reported that the doping and pressure dependence of the $T^\ast(B)$ crossover in YbRh$2$Si$_2$ is incompatible with its interpretation as signature of a Kondo breakdown.

Grams,Joachim Hemberger,Petra Becker,P.H.M. van Loosdrecht,D. I. Khomskii,Jeroen van den Brink,Maria Hermanns,Mark F. Gruninger +18 more
TL;DR: In this paper , the mixed-valent iridate Ba 3 InIr 2 O 9 has been considered as a promising candidate for quantum spin-liquid behavior, and strong intradimer hopping delocalizes the three t 2 g holes in quasimolecular dimer states while interdimer charge suppression is suppressed by Coulomb repulsion.

TL;DR: The cubic intermetallic compound HoInCu$_4$ with all holmium atoms on an fcc lattice exhibits partial magnetic frustration, yielding a ground state where half of the Ho moments remain without long-range order as mentioned in this paper.
Journal ArticleDOI
Low-temperature specific heat of non-charge ordered Yb4(As0.36Sb0.64)3 and (Yb0.87Lu0.13)4As3
TL;DR: In this article, measurements down to 0.06k in magnetic fields up to 10 T have been performed for spin-glass freezing around 0.1 and 0.4 K for Yb4(As 0.36Sb 0.64)3 and (Yb0.87Lu 0.13)4As3, respectively.
Journal ArticleDOI
Nonlinear conductivity in CaRuO3 thin films measured by short current pulses
TL;DR: In this article, the nonlinear conductivity of high-quality CaRuO$_3$ thin films with residual resistivity ratio up to 57 was studied using micro-second short, high-field current pulses at low temperatures.
