Effective Ionic Valence and Local Magnetic Moment in Kagome Superconductors
Ruoshi Jiang, Zi-Jian Lang, Yuzki Oey +11
In order to understand the unexpected similarity and the correlated behavior in kagome superconductor families AVSb (A = K, Rb, Cs) and ATiBi (A = Rb, Cs), we inves…
Ultrasound Evidence for a Low-Temperature Anomaly Inside the Superconducting State of 4Hb-TaS
Yongwei Li, Dmitri V. Efremov, Paul Leask +7
We report low-temperature ultrasound measurements on single crystals of the layered van der Waals superconductor 4Hb-TaS. Specific heat and ac magnetic susceptibility show a sh…
Origins of spontaneous magnetic fields in SrRuO
Yongwei Li, Rustem Khasanov, Stephen P. Cottrell +5
The nature of the broken time reversal symmetry (BTRS) state in SrRuO remains elusive, and its relation to superconductivity remains controversial. There are various univer…
Novel coupling between charge order and time-reversal-symmetry-breaking superconductivity
Quanxin Hu, Lingfeng Zhang, Yu Zheng +9
The interplay between charge-density waves (CDWs), which break translational symmetry, and spatially homogeneous superconductivity, which breaks global U(1) gauge symmetry, can giv…
Nematic Fluctuations and Electronic Correlations in Heavily Hole-Doped BaKFeAs Probed by Elastoresistance
Franz Eckelt, Steffen Sykora, Xiaochen Hong +6
This work investigates nematic fluctuations and electronic correlations in the hole-doped iron pnictide superconductor BaKFeAs by means of longitudinal and tran…
Inhomogeneity-driven multiform Spontaneous Hall Effect in conventional and unconventional superconductors
Nadia Stegani, Ilaria Pallecchi, Nicola Manca +10
The spontaneous Hall effect (SHE), a finite voltage occurring transversal to the electrical current in zero-magnetic field, has been observed in both conventional and unconventiona…
Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of BaKFeAs
Florian Bärtl, Nadia Stegani, Federico Caglieris +13
Muon-spin-rotation (SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at above the supercon…
Observation of single-quantum vortex splitting in the BaKFeAs superconductor
Q. Z. Zhou, B. R. Chen, B. K. Xiang +12
Since their theoretical discovery more than a half-century ago, vortices observed in bulk superconductors have carried a quantized value of magnetic flux determined only by fundame…
Direct observation of quantum vortex fractionalization in multiband superconductors
Yu Zheng, Quanxin Hu, Haijiao Ji +13
Magnetic field is expelled from a superconductor, unless it forms quantum vortices, consisting of a core singularity with current circulating around it. The London quantization con…
Ultrasound evidence for multicomponent superconducting order parameter in BaKFeAs with electron quadrupling phase
Chris Halcrow, Ilya Shipulin, Federico Caglieris +6
Experiments have pointed to the formation of the electron quadrupling condensate in BaKFeAs at . The state spontaneously breaks time-reversal symmet…
Extraordinary physical properties of superconducting YBaSrCuOSe in a multiphase ceramic material
V. Grinenko, A. Dudka, S. Nozaki +10
We report on a novel material obtained by modifying pristine YBCO superconductor in solid phase synthesis via simultaneous partial substitution of Ba by Sr and O by Se. Simultaneou…
Long-range magnetic order in the triangular lattice antiferromagnet KCeS
G. Bastien, B. Rubrecht, E. Haeussler +19
Recently, several putative quantum spin liquid (QSL) states were discovered in rare-earth based triangular-lattice antiferromagnets (TLAF) with the delafossite s…
