Hard x-ray photoelectron diffraction (hXPD) patterns recorded with a momentum microscope with high k -resolution (0.025 Å ^−1 equivalent to an angular resolution of 0.034° at 7 keV) reveal unprecedented rich fine structure. We have studied hXPD o

Imaging energy filters in photoelectron microscopes and momentum microscopes use spherical fields with deflection angles of 90°, 180° and even 2 × 180°. These instruments are optimized for high energy resolution, and exhibit image aberrations whe

Photoelectron spectroscopy, especially at pulsed sources, is ultimately limited by the Coulomb interaction in the electron cloud, changing energy and angular distribution of the photoelectrons. A detailed understanding of this phenomenon is crucial f

Antiferromagnets offer faster operation speed and immunity to stray fields, however, readout of the Neel vector is difficult. Here, Bommanaboyena et al present a heterostructure of a ferromagnet and antiferromagnet, combining easy readout with the be

The zero net moment of antiferromagnets makes them insensitive to magnetic fields and enables ultrafast dynamics promising for novel spintronics. Here the authors achieved pulse current induced Néel vector switching in Mn2Au(001) epitaxial thin film

Using spin-resolved time-of-flight momentum microscopy, the Rashba splitting of the Tamm surface state is investigated. This state resides at the Fermi level in a projected bulk band gap of the close-packed (0001) surface of hcp Re. The Rashba splitt
