Selected Applications Premium Line - SPM measurements 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.

Kern, Max-Planck Institute for Solid State Research, Stuttgart, Germany) Al(100) T=15mK U=10mV I=1nA 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.
