Colossal magnetoresistance from spin-polarized polarons in an Ising system
Ying-Fei Li, Emily M. Been, Sudhaman Balguri +12
Recent experiments suggest a new paradigm towards novel colossal magnetoresistance (CMR) in a family of materials EuMX(M=Cd, In, Zn; X=P, As), distinct from the traditional…
Momentum Dependence of the Nematic Order Parameter in Iron-Based Superconductors
H. Pfau, S. D. Chen, M. Yi +11
The momentum dependence of the nematic order parameter is an important ingredient in the microscopic description of iron-based high-temperature superconductors. While recent report…
Detailed band structure of twinned and detwinned BaFeAs studied with angle-resolved photoemission spectroscopy
H. Pfau, C. R. Rotundu, J. C. Palmstrom +6
We study the band structure of twinned and detwinned BaFeAs using angle-resolved photoemission spectroscopy (ARPES). The combination of measurements in the ordered and norm…
Metallic surface states in a correlated d-electron topological Kondo insulator candidate FeSb2
Ke-Jun Xu, Su-Di Chen, Yu He +9
The resistance of a conventional insulator diverges as temperature approaches zero. The peculiar low temperature resistivity saturation in the 4f Kondo insulator (KI) SmB6 has spur…
Rapid change of superconductivity and electron-phonon coupling through 19% doping in Bi2212
Yu He, Makoto Hashimoto, Dongjoon Song +12
Electron-boson coupling plays a key role in superconductivity for many systems. However, in copper-based high-temperature () superconductors, its relation to superconductivity…
Dispersive charge density wave excitations and temperature dependent commensuration in Bi2Sr2CaCu2O8+δ
Laura Chaix, Giacomo Ghiringhelli, Yingying Peng +14
Experimental evidence on high-Tc cuprates reveals ubiquitous charge density wave (CDW) modulations, which coexist with superconductivity. Although the CDW had been predicted by the…
Distinct Electronic Structure for the Extreme Magnetoresistance in YSb
Junfeng He, Chaofan Zhang, Nirmal J. Ghimire +15
An extreme magnetoresistance (XMR) has recently been observed in several non-magnetic semimetals. Increasing experimental and theoretical evidence indicates that the XMR can be dri…
Angle-resolved Photoemission Spectroscopy Study on the Surface States of the Correlated Topological Insulator YbB6
M. Xia, J. Jiang, Z. R. Ye +10
We report the electronic structure of YbB6, a recently predicted moderately correlated topological insulator, measured by angle-resolved photoemission spectroscopy. We directly obs…
