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…
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…
