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…
Asymmetric Electrostatic Dodecapole: Compact Bandpass Filter with Low Aberrations for Momentum Microscopy
O. Tkach, S. Babenkov, Y. Lytvynenko +5
Imaging energy filters in photoelectron microscopes and momentum microscopes use spherical fields with deflection angles of 90°, 180°, and even 2 x 180°. These instruments are o…
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…
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…
Layered Multiple Scattering Approach to Hard X-ray Photoelectron Diffraction: Theory and Application
Trung-Phuc Vo, Olena Tkach, Sylvain Tricot +10
Photoelectron diffraction (PED) is a powerful and essential experimental technique for resolving the structure of surfaces with sub-angstrom resolution. In the high energy regime,…
