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…
The electronic structure of EuPdSi in the vicinity of the critical endpoint
O. Fedchenko, Y. -J. Song, O. Tkach +10
Hard X-ray angle-resolved photoemission spectroscopy reveals significant alterations in the valence band states of EuPdSi at a temperature , where the Eu ions undergo…
