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…
Stabilizing perpendicular magnetic anisotropy with strong exchange bias in PtMn/Co by magneto-ionics
Beatrice Bednarz, Maria-Andromachi Syskaki, Rohit Pachat +7
Electric field control of magnetic properties offers a broad and promising toolbox for enabling ultra-low power electronics. A key challenge with high technological relevance is to…
Magneto-ionic modulation of the interlayer exchange interaction in synthetic antiferromagnets
Maria-Andromachi Syskaki, Takaaki Dohi, Sergei Olegovich Filnov +13
The electric-field control of magnetism is a highly promising and potentially effective approach for achieving energy-efficient applications. In recent times, there has been signif…
Higher-order Hall response arises from octupole order and scalar spin chirality in a noncollinear antiferromagnet
Adithya Rajan, Tom G. Saunderson, Fabian R. Lux +19
Noncollinear antiferromagnets can generate a transverse electrical response known as the anomalous Hall effect, even though they possess almost no net magnetization. The microscopi…
Mechanism of electrical switching of ultra-thin CoO/Pt bilayers
Christin Schmitt, Adithya Rajan, Grischa Beneke +9
We study current-induced switching of the Néel vector in CoO/Pt bilayers to understand the underlaying antiferromagnetic switching mechanism. Surprisingly, we find that for ultra-t…
Laser-induced Creation of antiferromagnetic 180-degree domains in NiO/Pt bilayers
Hendrik Meer, Stephan Wust, Christin Schmitt +15
We demonstrate how the antiferromagnetic order in heterostructures of NiO/Pt thin films can be modified by optical pulses. We irradiate our samples with laser light and identify an…
