Tilted spin current generated by the collinear antiferromagnet RuO2
Arnab Bose, Nathaniel J. Schreiber, Rakshit Jain +8
We report measurements demonstrating that when the Neel vector of the collinear antiferromagnet RuO2 is appropriately canted relative to the sample plane, the antiferromagnet gener…
Emergent chirality in a polar meron to skyrmion phase transition
Yu-Tsun Shao, Sujit Das, Zijian Hong +10
Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya…
Operando Control of Skyrmion Density in a Lorentz Transmission Electron Microscope with Current Pulses
Albert M. Park, Zhen Chen, Xiyue S. Zhang +3
Magnetic skyrmions hold promise for spintronic devices. To explore the dynamical properties of skyrmions in devices, a nanoscale method to image spin textures in response to a stim…
Role of Dirac nodal lines and strain on the high spin Hall conductivity of epitaxial IrO2 thin films
Arnab Bose, Jocienne N. Nelson, Xiyue S. Zhang +6
Since the discovery of a 'giant' spin Hall effect (SHE) in certain heavy metal elements there has been an intense effort to identify and develop new and technologically viable, hea…
Atomically-thin Ohmic Edge Contacts Between Two-dimensional Materials
Marcos H. D. Guimaraes, Hui Gao, Yimo Han +6
With the decrease of the dimensions of electronic devices, the role played by electrical contacts is ever increasing, eventually coming to dominate the overall device volume and to…
Nanomaterial datasets to advance tomography in scanning transmission electron microscopy
Barnaby D. A. Levin, Elliot Padgett, Chien-Chun Chen +17
Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for devel…
