Robust Weyl Semimetal and Pressure-induced Superconductivity in Quasi-One-Dimensional (NbSe4)2I
Cuiying Pei, Wujun Shi, Yi Zhao +15
A search for the single material system that simultaneously exhibits topological phase and intrinsic superconductivity has been largely limited, although such a system is far more…
Suppression of axionic charge density wave and onset of superconductivity in the chiral Weyl semimetal TaSeI
Qing-Ge Mu, Dennis Nenno, Yan-Peng Qi +7
A Weyl semimetal with strong electron-phonon interaction can show axionic coupling in its insulator state at low temperatures, owing to the formation of a charge density wave (CDW)…
Magnetic-field-induced FM-AFM metamagnetic transition and strong negative magnetoresistance in MnNbS under pressure
S. Polesya, S. Mankovsky, P. G. Naumov +6
Transition metal dichalcogenides (TMDC) stand out with their high chemical stability and the possibility to incorporate a wide range of magnetic species between the layers. The beh…

Pavel G. Naumov, Kai Filsinger, Sergii I. Shylin +8
The crystal structure, magnetic ordering, and electrical resistivity of TlFe1.6Se2 were studied at high pressures. Below ~7 GPa, TlFe1.6Se2 is an antiferromagnetically ordered semi…
Topological quantum phase transition and superconductivity induced by pressure in the bismuth tellurohalide BiTeI
Yanpeng Qi, Wujun Shi, Pavel G. Naumov +8
A pressure-induced topological quantum phase transition has been theoretically predicted for the semiconductor BiTeI with giant Rashba spin splitting. In this work, the evolution o…
Pressure-driven Superconductivity in Transition-metal Pentatelluride HfTe5
Yanpeng Qi, Wujun Shi, Pavel G. Naumov +8
Layered transition-metal tellurides have attracted considerable attention because of their rich physics; for example, tungsten ditelluride WTe2 exhibits extremely large magnetoresi…
Suppression of the ferromagnetic order in the Heusler alloy Ni50Mn35In15 by hydrostatic pressure
C. Salazar Mejia, K. Mydeen, P. Naumov +7
We report the effect of hydrostatic pressure on the magnetic and structural properties of the shape-memory Heusler alloy Ni50Mn35In15. Magnetization and x-ray diffraction experimen…
