Who said that AFM probes can only be used for Atomic Force Microscopy?
In the article “Resonant torsion magnetometry in anisotropic quantum materials” which just appeared in Nature Communications, K. A. Modic, Maja D. Bachmann, B. J. Ramshaw, F. Arnold, K. R. Shirer, Amelia Estry, J. B. Betts, Nirmal J. Ghimire, E. D. Bauer, Marcus Schmidt, Michael Baenitz, E. Svanidze, Ross D. McDonald, Arkady Shekhter and Philip J. W. Moll use the NANOSENSORS™ Akiyama-probe for resonant torsion magnetometry.
There are three advantages why it makes sense to divert the NANOSENSORS™ Akiyama-probe from it’s orginal intended use and use it for resonant torque magnetometry instead:
1. the relatively large spring constant of the silicon cantilever allows the authors to extend ultrasensitive and dynamic cantilever magnetometry to macroscopic sample sizes
- “the placement of the sample on the silicon cantilever (rather than one leg of a quartz tuning fork) eliminates complications that arise from the center of mass motion of the tuning fork coupling to the resonance mode
3. the electrical read-out of the A-probe eliminates the need for optical detection of the resonant frequency, thus making setup relatively straightforward and more robust compared to previous approaches.”*
