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…
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…
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…
