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…
Phonon-induced pseudogap phase in TiSe
Sotirios Fragkos, Nina Girotto Erhardt, Evgenia Symeonidou +9
To comprehend quantum ordered states, such as charge density waves (CDW), in layered transition metal dichalcogenides (TMDCs), it is essential to uncover their underlying normal st…
Electronic Structure and Resonant Circular Dichroism of LaSrMnO from Soft X-ray Angle-Resolved Photoemission
Ãyvind Finnseth, Damian Brzozowski, Anders Christian Mathisen +12
Coupling between spin, orbital, charge, and lattice degrees of freedom in transition-metal oxides produces a variety of electronic and magnetic phenomena of importance for future t…
Electron-phonon-dominated charge-density-wave fluctuations in TiSe accessed by ultrafast nonequilibrium dynamics
Sotirios Fragkos, Hibiki Orio, Nina Girotto Erhardt +17
The complex phase diagram of 1T-TiSe2 consists of a charge density wave (CDW) below 200 K, and CDW fluctuations of still unknown origin at higher temperatures. Here, we use time-re…
Direct signatures of -level hybridization and dimerization in magnetic adatom chains on a superconductor
Lisa M. Rütten, Eva Liebhaber, Gael Reecht +2
Magnetic adatom chains on superconductors provide a platform to explore correlated spin states and emergent quantum phases. Using low-temperature scanning tunneling spectroscopy, w…
3D atomic structure determination with ultrashort-pulse MeV electron diffraction
Vincent Hennicke, Max Hachmann, Paul Benjamin Klar +22
Understanding structure at the atomic scale is fundamental for the development of materials with improved properties. Compared to other probes providing atomic resolution, electron…
