Elastoresistivity of heavily hole doped 122 iron pnictides superconductors
Xiaochen Hong, Steffen Sykora, Federico Caglieris +8
Nematicity in the heavily hole-doped iron pnictide superconductors remains controversial. Sizeable nematic fluctuations and even nematic orders far from a magnetic instability were…
Ubiquitous enhancement of nematic fluctuations across the phase diagram of iron based superconductors probed by the Nernst effect
Christoph Wuttke, Federico Caglieris, Steffen Sykora +11
The role of nematic fluctuations for unconventional superconductivity has been subject of intense discussions for many years. In iron-based superconductors, the most established pr…
Quartic metal: Spontaneous breaking of time-reversal symmetry due to four-fermion correlations in BaKFeAs
Vadim Grinenko, Daniel Weston, Federico Caglieris +19
Discoveries of ordered quantum states of matter are of great fundamental interest, and often lead to unique applications. The most well known example -- superconductivity -- is cau…
Revisiting the phase diagram of LaFeCoAsO on single crystals by thermodynamic methods
Francesco Scaravaggi, Sven Sauerland, Liran Wang +13
In this work we revisit the phase diagram of Co-doped LaFeAsO using single crystals and thermodynamic methods. From magnetic susceptibility studies we track the doping evolution of…
High-field thermal transport properties of the Kitaev quantum magnet alpha-RuCl3: evidence for low-energy excitations beyond the critical field
Richard Hentrich, Xiaochen Hong, Matthias Gillig +11
We investigate the phononic in-plane longitudinal low-temperature thermal conductivity kappa_ab of the Kitaev quantum magnet alpha-RuCl3 for large in-plane magnetic fields up to 33…
Polymorphic PtBi2: Growth, structure and superconducting properties
G. Shipunov, I. Kovalchuk, B. R. Piening +13
PtBi is a polymorphic system with interesting electronic properties. Here we report optimized crystal growth and structural characterization of pyrite-type and trigonal modific…
