Twofold Symmetry Observed in BiTe/FeTe Interfacial Superconductor
Xinru Han, Hailang Qin, Tianluo Pan +10
Superconducting pairing symmetry are crucial in understanding the microscopic superconducting mechanism of a superconductor. Here we report the observation of a twofold superconduc…
The s-Wave Pairing and the Destructive Role of Apical-Oxygen Deficiencies in LaNiO Under Pressure
Yu-Bo Liu, Jia-Wei Mei, Fei Ye +2
Recently, the bilayer perovskite nickelate LaNiO has been reported to show evidence of high-temperature superconductivity (SC) under a moderate pressure of about 14 GPa…
Lattice dynamics in the charge-density-wave metal at a van-Hove-singularity filling
Jia-Wei Mei, Fei Ye, Xiaobin Chen
The charge-density-wave (CDW) order with macroscopically occupied electrons distorts the underlying lattice and usually causes the softening of the associated phonon mode. However,…
Dynamic fingerprint of fractionalized excitations in single-crystalline CuZn(OH)FBr
Ying Fu, Miao-Ling Lin, Le Wang +14
Quantum spin liquid (QSL) represents a new class of condensed matter states characterized by the long-range many-body entanglement of topological orders. The most prominent feature…
Surface-induced linear magnetoresistance in antiferromagnetic topological insulator MnBi2Te4
X. Lei, L. Zhou, Z. Y. Hao +10
Through a thorough magneto-transport study of antiferromagnetic topological insulator MnBi2Te4 (MBT) thick films, a positive linear magnetoresistance (LMR) with a two-dimensional (…
Core-level x-ray photoemission and Raman spectroscopy studies on electronic structures in Mott-Hubbard type nickelate oxide NdNiO
Ying Fu, Le Wang, Hu Cheng +14
We perform core-level X-ray photoemission spectroscopy (XPS) and electronic Raman scattering studies of electronic structures and spin fluctuations in the bulk samples of the nicke…
Effective Hamiltonian for superconducting Ni oxides NdSrNiO
Hu Zhang, Lipeng Jin, Shanmin Wang +4
We derive the effective single-band Hamiltonian in the flat NiO planes for nickelate compounds NdSrNiO. We first implement the first-principles calculation to s…
Magnetic Raman continuum in single crystalline HLiIrO
Shenghai Pei, Liang-Long Huang, Gaomin Li +10
Recently HLiIrO has been reported as a spin-orbital entangled quantum spin liquid (QSL) [K. Kitagawa et al., Nature {\bf 554}, 341 (2018)], albeit its connection to Kit…
Fluctuation-Induced Interactions and the Spin Glass Transition in
P. G. LaBarre, D. Phelan, Y. Xin +6
We investigate the spin-glass transition in the strongly frustrated well-known compound . A remarkable feature of this transition, widely discussed in the literature, is…
Molecular Beam Epitaxy Grown Thin Films with Tunable Curie Temperatures
Hongxi Li, Linjing Wang, Tao Yu +6
Materials with perpendicular magnetic anisotropy (PMA) effect with high Curie temperature () is essential in applications. In this work, thin films showing PMA with…
Topological Hall effect in bulk ferromagnet CrTe embedded with black-phosphorus-like bismuth nanosheets
Liang Zhou, Junshu Chen, Xiaobin Chen +14
We implement the molecular beam epitaxy method to embed the black-phosphorus-like bismuth nanosheets into the bulk ferromagnet CrTe. As a typical surfactant, bismuth lowers…
Interfacial superconductivity induced by single-quintuple-layer BiTe on top of FeTe forming van-der-Waals heterostructure
Hailang Qin, Bin Guo, Linjing Wang +14
We report the first clear observation of interfacial superconductivity on top of FeTe(FT) covered by one quintuple-layer BiTe(BT) forming van-der-Waals heterojunction. Both…
Raman evidence for dimerization and Mott collapse in -RuCl under pressures
Gaomin Li, Xiaobin Chen, Yuan Gan +16
We perform Raman spectroscopy studies on -RuCl at room temperature to explore its phase transitions of magnetism and chemical bonding under pressures. The Raman measurements…
