Realization of a Type-II Nodal-Line Semimetal in MgBi
Tay-Rong Chang, Ivo Pletikosic, Tai Kong +9
Nodal-line semimetals (NLSs) represent a new type of topological semimetallic beyond Weyl and Dirac semimetals in the sense that they host closed loops or open curves of band degen…
Anisotropic magnetic properties of the ferromagnetic semiconductor CrSbSe
Tai Kong, Karoline Stolze, Ni Danrui +2
Single crystals of CrSbSe, a structurally pseudo-one-dimensional ferromagnetic semiconductor, were grown using a high-temperature solution growth technique and were characteriz…
Observation of the Quantum Spin Hall Effect up to 100 Kelvin in a Monolayer Crystal
Sanfeng Wu, Valla Fatemi, Quinn D. Gibson +4
The field of topological insulators (TI) was sparked by the prediction of the quantum spin Hall effect (QSHE) in time reversal invariant systems, such as spin-orbit coupled monolay…
Possible quadrupolar nematic phase in the frustrated spin chain LiCuSbO: an NMR investigation
Marko Bosiočić, Fabrice Bert, Siân E. Dutton +4
The frustrated one-dimensional (1D) quantum magnet LiCuSbO is one rare realization of the spin chain model with an easily accessible saturation field, formerly estima…
Superconductivity in the Nb-Ru-Ge -Phase
Elizabeth M. Carnicom, Weiwei Xie, Zuzanna Sobczak +3
We show that the previously unreported ternary -phase material NbRuGe is a superconductor with a critical temperature of 2.2 K. Temperature-dependent ma…
Zero resistance from one atmosphere to the pressure of earth's outer core in a superconducting high entropy alloy
Jing Guo, Honghong Wang, Fabian von Rohr +9
We report the observation of extraordinarily robust zero-resistance superconductivity in the pressurized (TaNb)0.67(HfZrTi)0.33 high entropy alloy - a new kind of material with a b…
