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…
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…
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…
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…
Imaging strain-controlled magnetic reversal in thin CrSBr
Kousik Bagani, Andriani Vervelaki, Daniel Jetter +9
Two-dimensional materials are extraordinarily sensitive to external stimuli, making them ideal for studying fundamental properties and for engineering devices with new functionalit…
Imaging magnetic spiral phases, skyrmion clusters, and skyrmion displacements at the surface of bulk CuOSeO
E. Marchiori, G. Romagnoli, L. Schneider +8
Surfaces -- by breaking bulk symmetries, introducing roughness, or hosting defects -- can significantly influence magnetic order in magnetic materials. Determining their effect on…
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…
Nanoscale magnetism and magnetic phase transitions in atomically thin CrSBr
Märta A. Tschudin, David A. Broadway, Patrick Reiser +13
Since their first observation in 2017, atomically thin van der Waals (vdW) magnets have attracted significant fundamental, and application-driven attention. However, their low orde…
Visualizing thickness-dependent magnetic textures in few-layer
Andriani Vervelaki, Kousik Bagani, Daniel Jetter +6
Magnetic ordering in two-dimensional (2D) materials has recently emerged as a promising platform for data storage, computing, and sensing. To advance these developments, it is vita…
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…
