Multi-Mode Lens for Momentum Microscopy and XPEEM: Theory
Olena Tkach, Gerd Schoenhense
The strong electric field between the sample and the extractor is the core of cathode lenses and a pivotal determinant of high resolution. Nevertheless, fields in the range of 3-8…
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 opti…
Structure Analysis using Time-of-Flight Momentum Microscopy with Hard X-rays: Status and Prospects
Olena Fedchenko, Aimo Winkelmann, Gerd Schönhense
X-ray photoelectron diffraction (XPD) has developed into a powerful technique for the structural analysis of solids. Extension of the technique into the hard-X-ray range (hXPD) giv…
Direct Observation of Antiferromagnetic Parity Violation in the Electronic Structure of MnAu
Olena Fedchenko, Libor Smejkal, Michael Kallmayer +10
Parity symmetric photoemission spectra are ubiquitous in solid state research, being prevalent in many highly active areas, such as unconventional superconductors, nonmagnetic and…
Hard x-ray angle-resolved photoemission from a buried high-mobility electron system
Michael Zapf, Matthias Schmitt, Judith Gabel +18
Novel two-dimensional electron systems at the interfaces and surfaces of transition-metal oxides recently have attracted much attention as they display tunable, intriguing properti…
Subpicosecond metamagnetic phase transition driven by non-equilibrium electron dynamics
Federico Pressacco, Davide Sangalli, Vojtěch Uhlíř +13
Femtosecond light-induced phase transitions between different macroscopic orders provide the possibility to tune the functional properties of condensed matter on ultrafast timescal…
