Orbital Hall effect and orbital altermagnetism in even- and odd-parity-wave magnetic Lieb lattices
Börge Göbel, Ersoy Şaşıoğlu, Samir Lounis
Altermagnets combine compensated antiferromagnetic order with ferromagnet-like signatures such as spin-polarized bands and, under appropriate conditions, an anomalous Hall response…
Orbital and Spin Edelstein Effects in KTaO(110) Two-Dimensional Electron Gases
Hugo Witt, Aravind Raji, Srijani Mallik +16
The orbital Edelstein effect converts an electric field into a non-equilibrium orbital polarization, opening new opportunities for orbitronics. Although signatures of the orbital E…
Exact theory of chirality-dependent p-wave magnetism and Edelstein effect in spin spirals
Börge Göbel, Tom G. Saunderson, Freia Opfermann +3
Spin-momentum locking is widely regarded as a hallmark of relativistic spin-orbit coupling. Here we demonstrate analytically that it can instead emerge solely from magnetic chirali…
Chiral-Angle-Controlled Spin Splitting and Spin Transport in Nanotubes Rolled from d-wave Altermagnets
Ersoy Sasioglu, Tom. G. Saunderson, Börge Göbel +2
Altermagnets combine compensated collinear magnetic order with momentum-dependent spin splitting in the electronic band structure. Here, we show that rolling a two-dimensional (2D)…
Spontaneous nonreciprocal transport in a gate-tunable ferromagnetic Rashba 2-dimensional electron gas
Gabriel Lazrak, Radu Abrudan, Borge Göbel +10
The broken inversion symmetry at interfaces of complex oxides gives rise to emergent phenomena, including ferromagnetism and Rashba spin-orbit coupling (SOC), which profoundly infl…
Circular motion of non-collinear spin textures in Corbino disks: Dynamics of Néel- versus Bloch-type skyrmions and skyrmioniums
Ismael Ribeiro de Assis, Ingrid Mertig, Börge Göbel
Magnetic skyrmions are nano-scale magnetic whirls that can be driven by currents via spin torques. They are promising candidates for spintronic devices such as the racetrack memory…
Electronic bandstructure of superconducting KTaO3 (111) interfaces
Srijani Mallik, Börge Göbel, Hugo Witt +17
Two-dimensional electron gases(2DEGs)based on KTaO3 are emerging as a promising platform for spin-orbitronics due to their high Rashba spin-orbit coupling (SOC) and gate-voltage tu…
Boosting the Edelstein effect of two-dimensional electron gases by ferromagnetic exchange
Gabriel Lazrak, Börge Göbel, Agnès Barthélémy +3
Strontium titanate (SrTiO) two-dimensional electron gases (2DEGs) have broken spatial inversion symmetry and possess a finite Rashba spin-orbit coupling. This enables the inter…
Skyrmion motion in magnetic anisotropy gradients: Acceleration caused by deformation
Ismael Ribeiro de Assis, Ingrid Mertig, Börge Göbel
Magnetic skyrmions are nano-sized topologically non-trivial spin textures that can be moved by external stimuli such as spin currents and internal stimuli such as spatial gradients…
Ultrafast Orbital Hall Effect in Metallic Nanoribbons
Oliver Busch, Franziska Ziolkowski, Börge Göbel +2
The orbital Hall effect can generate currents of angular momentum more efficiently than the spin Hall effect in most metals. However, so far, it has only been understood as a stead…
Orbital Hall effect and orbital edge states caused by s electrons
Oliver Busch, Ingrid Mertig, Börge Göbel
An orbital current can be generated whenever an object has a translational and rotational degree of freedom. In condensed matter physics, intra-atomic contributions to the transver…
Generation of out-of-plane polarized spin current by spin swapping
Binoy K. Hazra, Banabir Pal, Jae-Chun Jeon +9
The generation of spin currents and their application to the manipulation of magnetic states is fundamental to spintronics. Of particular interest are chiral antiferromagnets that…
Biskyrmion-based artificial neuron with refractory period
Ismael Ribeiro de Assis, Ingrid Mertig, Börge Göbel
Magnetic skyrmions are nanoscale magnetic whirls that are highly stable and can be moved by currents which has led to the prediction of a skyrmion-based artificial neuron device wi…
Direct visualization of Rashba-split bands and spin/orbital-charge interconversion at KTaO interfaces
Sara Varotto, Annika Johansson, Börge Göbel +10
Rashba interfaces have emerged as promising platforms for spin-charge interconversion through the direct and inverse Edelstein effects. Notably, oxide-based two-dimensional electro…
Signatures of lattice geometry in quantum and topological Hall effect
Börge Göbel, Alexander Mook, Jürgen Henk +1
The topological Hall effect (THE) of electrons in skyrmion crystals is strongly related to the quantum Hall effect (QHE) on lattices. This relation suggests to revisit the QHE beca…
