Observation of superconductivity in pressurized Weyl semimetal candidate TaIrTe4
Shu Cai, Eve Emmanouilidou, Jing Guo +7
Here we report the observation of superconductivity in pressurized type-II Weyl semimetal (WSM) candidate TaIrTe4 by means of complementary high-pressure transport and synchrotron…
Possible High TC Layered Ferromagnetic Insulator Sr2NiRuO4: An ab initio Study
Ke Yang, Feng-Ren Fan, Alessandro Stroppa +1
Magnetic insulators are often antiferromagnetic (AFM) and layered AFM compounds usually show low ordering temperature. On the other hand, layered ferromagnetic (FM) insulators with…
Universal superconductivity phase diagram for pressurized tetradymite topological insulators
Shu Cai, S. K. Kushwaha, Jing Guo +13
We show that two different superconducting phases exist at high pressures in the optimized tetradymite topological insulators Bi2Te2Se (BTS) and Bi1.1Sb0.9Te2S (BSTS). The supercon…
Record-High Superconductivity in Niobium-Titanium Alloy
Jing Guo, Gongchang Lin, Shu Cai +11
Here we report the observation of extraordinary superconductivity in a pressurized commercial niobium-titanium alloy. We find that its zero-resistance superconductivity persists fr…
Independence of topological surface state and bulk conductances in three-dimensional topological insulators
Shu Cai, Jing Guo, Vladimir A. Sidorov +12
The archetypical 3D topological insulators Bi2Se3, Bi2Te3 and Sb2Te3 commonly exhibit high bulk conductivities, hindering the characterization of the surface state charge transport…
Unusual layered order and charge disproportionation in double perovskite Ca2FeMnO6
Ke Yang, D. I. Khomskii, Hua Wu
While double perovskites A2BB'O6, if ordered, usually form a rock-salt-type structure with a checkerboard B/B' ordering, it is surprising that Ca2FeMnO6 has alternate FeO2 and MnO2…
