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…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. Biało, 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…
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…
ARPES studies of Hf(0001) surface: flat bands formation in the dice lattice
Laxman Nagireddy, Saleem Ayaz Khan, Maria Christine Richter +8
We present the first electronic structure measurements of the Hf(0001) single-crystal surface using angle-resolved photoemission spectroscopy (ARPES). The ARPES results are support…
Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…
Observation of the Dirac Dispersions in Co-doped CaFe2As2
Marcin Rosmus, Natalia Olszowska, Rafal Kurleto +2
We performed an angle-resolved photoemission spectroscopy (ARPES) study of the electronic structure of the CaFeAs 122-iron pnictide, a parent compound, and two iron-based s…
