Spatial resolution and point spread function of high-resolution scanning SQUID microscopy probes
Jan Ullmann, Katharina Kress, Timur Weber +5
Superconducting quantum interference devices (SQUIDs) show exceptional sensitivity to magnetic flux. In scanning SQUID microscopy (SSM), SQUID size and its distance to the sample a…
Imaging short- and long-range magnetic order in a quantum anomalous Hall insulator
Andriani Vervelaki, Boris Gross, Daniel Jetter +11
The quantum anomalous Hall effect has been observed in several magnetically doped topological insulators, where its robustness and macroscopic magnetization properties have been ta…
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…
Lateral Exchange Bias for Néel-Vector Control in Atomically Thin Antiferromagnets
Clément Pellet-Mary, Debarghya Dutta, Märta A. Tschudin +10
Atomically thin van der Waals (vdW) magnets have emerged as a fascinating platform for the exploration of novel physical phenomena arising from their reduced dimensionality and exc…
Advanced SQUID-on-lever scanning probe for high-sensitivity magnetic microscopy with sub-100-nm spatial resolution
Timur Weber, Daniel Jetter, Jan Ullmann +13
Superconducting quantum interference devices (SQUIDs) are exceptionally sensitive magnetometers capable of detecting weak magnetic fields. Miniaturizing these devices and integrati…
Imaging magnetic switching in orthogonally twisted stacks of a van der Waals antiferromagnet
Alexander J Healey, Cheng Tan, Boris Gross +9
Stacking van der Waals magnets holds promise for creating new hybrid materials with properties that do not exist in bulk materials. Here we investigate orthogonally twisted stacks…
