Superconducting dome and field-enhanced superconductivity of PLD synthesized Nd1-xEuxNiO2 thin films
Wenlong Yang, Qiang Zhao, Xingke Fu +8
We report on the synthesis of infinite-layer Nd1-xEuxNiO2 (0<x<0.7) thin films using pulsed laser deposition (PLD) followed by topotactic reduction with CaH2. Resistivity measureme…
Anomalous Structural Response of Quasi-One-Dimensional Antiferromagnetic Metal KMn6Bi5 under high pressure
Hanming Ma, Qingxin Dong, Tong Shi +11
We report high-pressure single-crystal X-ray diffraction measurements on the quasi-one-dimensional (Q1D) antiferromagnetic metal KMn6Bi5 up to 12.5 GPa, revealing the detailed pres…
Structural responses incipient to pressure-driven antiferromagnetic quantum critical point of van der Waals heavy-fermion metal CeSiI
Hanming Ma, Tong Shi, Wenhao Li +12
CeSiI is a van der Waals heavy-fermion metal recently found to exhibit unconventional superconductivity near a pressure-induced antiferromagnetic quantum critical point (QCP) at Pc…
Two distinct superconducting regimes in Ti4Co2O under pressures
Lifen Shi, Keyuan Ma, Binbin Ruan +8
We report on the pressure dependence of superconducting transition temperature Tc and upper critical field Bc2(0) through electrical transport of the Ti4Co2O superconductor (eg.,th…
Emergent Polar Metal Phase in a Van der Waals Mott Magnet
Shiyu Deng, Matthew J. Coak, Charles R. S. Haines +16
We report the emergence of a two-dimensional (2D) polar metal phase in van der Waals compound FePSe under moderate pressures. This layered material is a Mott insulator with ant…
Superconductivity under pressure in the two-dimensional van der Waals heavy-fermion metal CeSiI
Tong Shi, Wenhao Li, Qingxin Dong +10
CeSiI is a newly discovered exfoliable van der Waals (vdW) heavy-fermion metal featured by a long-range antiferromagnetic (AF) order (TN =7.5 K) inside the Kondo coherent state bel…
