Epitaxial growth and magnetic phase transitions in non-centrosymmetric EuPdSi thin films
Sebastian Kölsch, Alfons G. Schuck, Olena Fedchenko +9
Non-centrosymmetric magnetic materials are a promising platform for stabilizing chiral spin textures, such as skyrmions and cycloidal magnetic states. This is particularly true in…
Multimode Objective Lens for Momentum Microscopy and XPEEM: Experiments
O. Tkach, S. Fragkos, D. Biswas +37
A new type of objective lens has recently been proposed for use in X-ray photoemission electron microscopes (XPEEMs) and momentum microscopes. Adding a ring electrode concentric wi…
Orbital magnetization in the Nb-substituted Kagome metal CsVSb
H. J. Elmers, O. Tkach, Y. Lytvynenko +12
This study uses angle-resolved photoemission spectroscopy to examine the low-temperature electronic structure of Cs(VNb)Sb, demonstrating that partially s…
Time- and Polarization-Resolved Extreme Ultraviolet Momentum Microscopy
Sotirios Fragkos, Quentin Courtade, Olena Tkach +7
We report the development of an instrument combining an ultrafast, high-repetition-rate, polarization-tunable monochromatic extreme ultraviolet (XUV, 21.6 eV) beamline and a next-g…
Unveiling Fine Structure and Energy-driven Transition of Photoelectron Kikuchi Diffraction
Trung-Phuc Vo, Olena Tkach, Aki Pulkkinen +8
The intricate fine structure of Kikuchi diffraction plays a vital role in probing phase transformations and strain distributions in functional materials, particularly in electron m…
GeSi single crystals for Ge hole spin qubit integration
Andreas Fuhrberg, Pia M. Düring, Olena Fedchenko +9
Spin qubits are fundamental building blocks of modern quantum computing devices. The path of Ge-based hole-spin qubits has several advantages over Si-based electron-spin systems, s…
