Anomalous Hall resistivity and possible topological Hall effect in the EuAl antiferromagnet
T. Shang, Y. Xu, D. J. Gawryluk +4
We report the observation of anomalous Hall resistivity in single crystals of EuAl, a centrosymmetric tetragonal compound, which exhibits coexisting antiferromagnetic (AFM) and…
Multigap superconductivity in the MoPB boron-phosphorus compound
T. Shang, W. Xie, D. J. Gawryluk +7
The tetragonal MoPB compound was recently reported to show superconductivity with a critical temperature up to 9.2 K. In search of evidence for multiple superconducting gap…
Superconductivity and topological aspects of the rock-salt carbides NbC and TaC
T. Shang, J. Z. Zhao, D. J. Gawryluk +4
Superconducting materials with a nontrivial band structure are potential candidates for topological superconductivity. Here, by combining muon-spin rotation and relaxation (SR)…
Short-range magnetic interactions and spin-glass behavior in the quasi-2D nickelate Pr4Ni3O8
Shangxiong Huangfu, Zurab Guguchia, Denis Cheptiakov +6
The nickelate Pr4Ni3O8 features quasi-two-dimensional layers consisting of three stacked square-planar NiO2 planes, in a similar way to the well-known cuprate superconductors. The…
Magnetic order and disorder in a quasi-two-dimensional quantum Heisenberg antiferromagnet with randomized exchange
F. Xiao, W. J. A. Blackmore, B. M. Huddart +13
We present an investigation of the effect of randomizing exchange strengths in the square lattice quasi-two-dimensional quantum Heisenberg antiferromagnet (QuinH)Cu(Cl$…
Observation of flat bands due to band hybridization in 3d-electron heavy-fermion compound CaCu3Ru4O12
Haijiang Liu, Yingying Cao, Yuanji Xu +7
We report angle-resolved photoemission spectroscopy and first-principles numerical calculations for the band structure evolution of the 3d heavy-fermion compound CaCu3Ru4O12. Below…
Topological Magnetic Phase in the Candidate Weyl Semimetal CeAlGe
P. Puphal, V. Pomjakushin, N. Kanazawa +9
We report the discovery of topological magnetism in the candidate magnetic Weyl semimetal CeAlGe. Using neutron scattering we find this system to host several incommensurate, squar…
Strong- to weak-coupling superconductivity in high- bismuthates: revisiting the phase diagram via SR
T. Shang, D. J. Gawryluk, M. Naamneh +6
Several decades after the discovery of superconductivity in bismuthates, the strength of their electron-phonon coupling and its evolution with doping remain puzzling. To clarify th…
