Anomalous Frequency Shift in Low-Loss Superconducting Granular Aluminum Resonators
Patrick Winkel, Daniil S. Antonenko, Vishakha Gupta +5
Superconducting high-kinetic inductance materials like granular aluminum (grAl) are a versatile part of the circuit quantum electrodynamics (cQED) toolbox, provided their losses at…
A quantized anomalous Hall effect above 4.2 K in stacked topological insulator/magnet bilayers
Rakshit Jain, Matthew Roddy, Vishakha Gupta +9
Quantized anomalous Hall effects (QAHEs) occur in remarkable electronic states which possess not only quantized Hall signals but in some cases regions of dissipationless electron t…
Low loss lumped-element inductors made from granular aluminum
Vishakha Gupta, Patrick Winkel, Neel Thakur +5
Lumped-element inductors are an integral component in the circuit QED toolbox. However, it is challenging to build inductors that are simultaneously compact, linear and low-loss wi…
Gate-tunable anomalous Hall effect in a 3D topological insulator/2D magnet van der Waals heterostructure
Vishakha Gupta, Rakshit Jain, Yafei Ren +8
We demonstrate advantages of samples made by mechanical stacking of exfoliated van der Waals materials for controlling the topological surface state of a 3-dimensional topological…
Separation of Artifacts from Spin-Torque Ferromagnetic Resonance Measurements of Spin-Orbit Torque for the Low-Symmetry van der Waals Semi-Metal ZrTe
Thow Min Cham, Saba Karimeddiny, Vishakha Gupta +2
We measure spin-orbit torque generated by exfoliated layers of the low-symmetry semi-metal ZrTe using the spin-torque ferromagnetic resonance (ST-FMR) technique. When the ZrTe$…
Layer-dependent spin-orbit torques generated by the centrosymmetric transition metal dichalcogenide -MoTe
Gregory M. Stiehl, Ruofan Li, Vishakha Gupta +8
Single-crystal materials with sufficiently low crystal symmetry and strong spin-orbit interactions can be used to generate novel forms of spin-orbit torques on adjacent ferromagnet…
