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…
Doping-Induced Electronic and Structural Phase Transition in the Bulk Weyl Semimetal Mo1-xWxTe2
O. Fedchenko, F. K. Diekmann, P. Russmann +21
A comprehensive study of the electronic and structural phase transition from 1T` to Td in the bulk Weyl semimetal Mo1-xWxTe2 at different doping concentrations has been carried out…
Control of the asymmetric band structure in Mn2Au by a ferromagnetic driver layer
Y. Lytvynenko, O. Fedchenko, S. V. Chernov +15
Hard X-ray angle-resolved photoemission spectroscopy reveals the momentum-resolved band structure in an epitaxial Mn2Au(001) film capped by a 2 nm thick ferromagnetic Permalloy lay…
Band structure tuning of Heusler compounds revisited: Spin- and momentum-resolved electronic structure analysis of compounds with different band filling
S. Chernov, C. Lidig, O. Fedchenko +3
Spin-filtered time-of-flight photoelectron momentum microscopy reveals a systematic variation of the band structure within a series of highly spin-polarized ferromagnetic Heusler c…
Breakthrough in HAXPES Performance Combining Full-Field k-Imaging with Time-of-Flight Recording
K. Medjanik, S. V. Babenkov, S. Chernov +8
We established a new approach to hard-X-ray photoelectron spectroscopy (HAXPES). The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D t…
Momentum-Transfer Model of Valence-Band Photoelectron Diffraction
G. Schoenhense, K. Medjanik, S. Babenkov +6
Owing to strongly enhanced bulk sensitivity, angle- or momentum-resolved photoemission using X-rays is an emergent powerful tool for electronic structure mapping. A novel full-fiel…
Spin Mapping of Surface and Bulk Rashba States in Ferroelectric a-GeTe(111) Films
H. J. Elmers, R. Wallauer, M. Liebmann +16
A comprehensive mapping of the spin polarization of the electronic bands in ferroelectric a-GeTe(111) films has been performed using a time-of-flight momentum microscope equipped w…
