Femtosecond all-optical coherent control of spin polarization in altermagnets
Kevin Jäckel, Holger Grisk, Niklas Dornquast +5
Altermagnets constitute an emerging materials platform for spintronic technologies by combining compensated magnetic order with ferromagnet-like spin-split electronic bands. Here,…
Surface-Localized Magnetic Order in RuO2 Thin Films Revealed by Low-Energy Muon Probes
Akashdeep Akashdeep, Sachin Krishnia, Jae-Hyun Ha +12
Ruthenium dioxide (RuO2) has recently emerged as a candidate altermagnet, yet its intrinsic magnetic ground state, particularly in thin films, remains debated. This study aims to c…
Depth Profiling of Oxygen Migration in Ta/HfO2 Stacks During Ionic Liquid Gating
Beatrice Bednarz, Martin Wortmann, Olga Kuschel +6
Ionic liquid (IL) gating has emerged as a powerful tool to control the structural, electronic, optical, and magnetic properties of materials by driving ion motion at solid interfac…
Surface Oxidation of SnTe Analyzed by Self-Consistent Fitting of all Emission Peaks in its X-ray Photoelectron Spectrum
Martin Wortmann, Beatrice Bednarz, Negin Beryani Nezafat +11
X-ray photoelectron spectroscopy (XPS) is among the most widely used methods for surface characterization. Currently, the analysis of XPS data is almost exclusively based on the ma…
Angle-Dependent Magnetoresistance Induced by Interface-Generated Spin Current in RuO/Permalloy Heterostructures
Akashdeep Akashdeep, Ewiese Mohammad Ababneh, Christin Schmitt +6
Altermagnets, a recently discovered class of magnetic materials exhibiting ferromagnetic-like spin-split bands and antiferromagnetic-like compensated magnetic order, have attracted…
