Growth of Altermagnetic α-MnTe Films: Substrate Variation and Surface Modification
M. Dittmar, L. Hirnet, H. Haberkamm +10
Manganese telluride (MnTe) in its hexagonal α-MnTe crystal structure has evolved as one of the altermagnet workhorse materials. The synthesis of MnTe thin films is highly relevant…
Surface states and Rashba-type spin polarization in antiferromagnetic MnBiTe
R. C. Vidal, H. Bentmann, T. R. F. Peixoto +32
The layered van der Waals antiferromagnet MnBiTe has been predicted to combine the band ordering of archetypical topological insulators such as BiTe with the magnet…
Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
Evidence of momentum dependent hybridization in Ce2Co0.8Si3.2
P. Starowicz, R. Kurleto, J. Goraus +7
We studied the electronic structure of the Kondo lattice system Ce2Co0.8Si3.2 by angle-resolved photoemission spectroscopy (ARPES). The spectra obtained below the coherence tempera…
A flat band at the chemical potential of a Fe1.03Te0.94S0.06 superconductor observed by angle-resolved photoemission spectroscopy
P. Starowicz, H. Schwab, J. Goraus +6
The electronic structure of superconducting Fe1.03Te0.94S0.06 has been studied by angle resolved photoemission spectroscopy (ARPES). Experimental band topography is compared to the…
