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…

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…
