Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic -MnTe
Mathews Benny, Xujia Gong, Amar Fakhredine +21
Altermagnetic -MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clar…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Magnetic Frustration Enforced Electronic Reconstruction in Ni intercalated NbSe: Suppression of Electronic Orders
Ashutosh S. Wadge, Alexander Kazakov, Xujia Gong +14
We investigate the single crystals of NiNbSe, revealing that Ni intercalation profoundly alters the physical properties of NbSe. Magnetic measurements clearly show…
Robust Orbital-Selective Flat Bands in Transition-Metal Oxychlorides
Xiangyu Luo, Ludovica Zullo, Sahaj Patel +10
Flat electronic bands, which amplify electron correlations by quenching kinetic energy, provide an ideal foundation for exotic quantum phases. However, prevailing strategies -- inc…
Experimental electronic structure of the mineral superconductor covellite CuS
Alexandre Antezak, Takemi Kato, Pedro Rezende Gonçalves +5
Covellite (CuS) is the first known natural mineral superconductor. Despite its simple chemical formula, covellite exhibits a rich crystal structure at the origin of several remarka…
Metallic layered materials with magnetic frustration: An ARPES view of the SmAuAlGe and TbAuAlGe
P. Rezende-Gonçalves, A. Antezak, T. Kato +10
Compounds of the new materials class LnTAlX (Ln = lanthanide, X = tetrel, T = transition metal) host exotic magnetic phenomena due to geometric frustration induced by their…
