Soft point-contact Andreev reflection spectroscopy in a palm-type cubic anvil-pressure cell
Qingxin Dong, Fengrui Shi, Yan Zhang +11
We have implemented soft point-contact Andreev reflection spectroscopy (PCARS) in a palm-type cubic anvil pressure cell by combining a substrate anchoring strategy with an external…
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…
Ising superconductivity and anomalous metallic states in a bulk crystal with artificial unidirectional stacking layers
Xiangqi Liu, Chen Xu, Haonan Wang +17
The two-dimensional (2D) limit in macroscopic bulk crystals provides a powerful platform for exploring exotic quantum phases. Here, we report the synthesis of a Sr0.75ClNbS2 superc…
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…
Metallic crossover through the tilt-free transition in LaNiO at high pressure and temperature
Bastien Michon, Yingpeng Yu, Beatrice D'Alò +8
LaNiO, a bilayer nickelate with Ruddlesden-Popper structure, undergoes a pressure-induced structural transition from a tilted Amam phase to an untilted Fmmm (or I4/mmm)…
