Antiferromagnetic insulatronics: spintronics in insulating 3d metal oxides with antiferromagnetic coupling
H. Meer, O. Gomonay, A. Wittmann +1
Antiferromagnetic transition metal oxides are an established and widely studied materials system in the context of spin-based electronics, commonly used as passive elements in exch…
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…
Identifiying the domain wall spin structure in current-induced switching of antiferromagnetic NiO/Pt
Christin Schmitt, Luis Sanchez-Tejerina, Mariia Filianina +9
The understanding of antiferromagnetic domain walls, which are the interface between domains with different Néel order orientations, is a crucial aspect to enable the use of antife…
Indirect optical manipulation of the antiferromagnetic order of insulating NiO by ultrafast interfacial energy transfer
Stephan Wust, Christopher Seibel, Hendrik Meer +14
We report the ultrafast, (sub)picosecond reduction of the antiferromagnetic order of the insulating NiO thin film in a Pt/NiO bilayer. This reduction of the antiferromagnetic order…
Strain-induced Shape Anisotropy in Antiferromagnetic Structures
Hendrik Meer, Olena Gomonay, Christin Schmitt +9
We demonstrate how shape-induced strain can be used to control antiferromagnetic order in NiO/Pt thin films. For rectangular elements patterned along the easy and hard magnetocryst…
Direct imaging of current-induced antiferromagnetic switching revealing a pure thermomagnetoelastic switching mechanism
H. Meer, F. Schreiber, C. Schmitt +6
We unravel the origin of current-induced magnetic switching of insulating antiferromagnet/heavy metal systems. We utilize concurrent transport and magneto-optical measurements to i…
