Magnetic properties of an individual Magnetospirillum gryphiswaldense cell
Mathias M. Claus, Marcus Wyss, Dirk Schüler +2
Many bacteria share the fascinating ability to sense Earth's magnetic field -- a process known as magnetotaxis. These bacteria synthesize magnetic nanoparticles, called magnetosome…
Enhanced Electron Spin Coherence in a GaAs Quantum Emitter
Giang N. Nguyen, Clemens Spinnler, Mark R. Hogg +10
A spin-photon interface should operate with both coherent photons and a coherent spin to enable cluster-state generation and entanglement distribution. In high-quality devices, sel…
Scanning NV magnetometry of focused-electron-beam-deposited cobalt nanomagnets
Liza Žaper, Peter Rickhaus, Marcus Wyss +3
Focused-electron-beam-induced deposition is a promising technique for patterning nanomagnets for spin qubit control in a single step. We fabricate cobalt nanomagnets in such a proc…
Transparent Josephson Junctions in Higher-Order Topological Insulator WTe2 via Pd Diffusion
Martin Endres, Artem Kononov, Michael Stiefel +7
Highly transparent superconducting contacts to a topological insulator (TI) remain a persistent challenge on the route to engineer topological superconductivity. Recently, the high…
Magnetic, thermal, and topographic imaging with a nanometer-scale SQUID-on-cantilever scanning probe
M. Wyss, K. Bagani, D. Jetter +7
Scanning superconducting quantum interference device (SQUID) microscopy is a magnetic imaging technique combining high-field sensitivity with nanometer-scale spatial resolution. St…
Imaging pinning and expulsion of individual superconducting vortices in amorphous MoSi thin films
L. Ceccarelli, D. Vasyukov, M. Wyss +4
We use a scanning nanometer-scale superconducting quantum interference device (SQUID) to image individual vortices in amorphous superconducting MoSi thin films. Spatially resolved…
Observation of vortex-nucleated magnetization reversal in individual ferromagnetic nanotubes
A. Mehlin, B. Gross, M. Wyss +6
The reversal of a uniform axial magnetization in a ferromagnetic nanotube (FNT) has been predicted to nucleate and propagate through vortex domains forming at the ends. In dynamic…
Imaging stray magnetic field of individual ferromagnetic nanotubes
D. Vasyukov, L. Ceccarelli, M. Wyss +11
We use a scanning nanometer-scale superconducting quantum interference device to map the stray magnetic field produced by individual ferromagnetic nanotubes (FNTs) as a function of…
Imaging magnetic vortex configurations in ferromagnetic nanotubes
M. Wyss, A. Mehlin, B. Gross +9
We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photo-emission electron microscopy. The images prov…
Magnetization reversal of an individual exchange biased permalloy nanotube
A. Buchter, R. Wölbing, M. Wyss +14
We investigate the magnetization reversal mechanism in an individual permalloy (Py) nanotube (NT) using a hybrid magnetometer consisting of a nanometer-scale SQUID (nanoSQUID) and…
