mK STM Image with Atomic Resolution
STM image of an aluminum (100) surface with atomic resolution. The
image size is about 29 x 20 nm². The corrugation is between 300fm and
800fm, depending on the direction of the line profile. Defects show up
as ring-like structures with different radii depending of their depth.
The image was measured in a homebuilt mK-STM at the Max-Planck
Institute for Solid State Research in Stuttgart, which uses an attocube
ANPz51 positioner for coarse approach.

Magnetic Resonance Imaging of Nanoscale Tobacco Mosaic
Virus at 300 mK
attocube’s ANPx51 positioners were used in an MRFM setup with the
task to precisely and reliably position a magnetic tip and a copper
nanowire to close proximity of an ultra-sensitive cantilever. The MRFM
setup was applied to investigate and reconstruct the 1H spin distribu-
tion of Tobacco Mosaic Virus particles, representing a 100-million fold
improvement in volume resolution over conventional MRI.
