Profile
The Working Group Nanomagnetism does research and development for precise measurements of nanomagnetic quantities. The main fields of work in this context are measurements of magnetization dynamics, local stray field measurements, as well as measurements of magneto thermo electric properties of magnetic nanostructures.
Research/Development
Magnetic imaging
In the field of magnetic imaging we focus on the characterization of nano patterned magnetic structures by magnetic force microscope (MFM) supported by measurements based on SQUID susceptometry, magnetotransport and magneto optics. Our priorities are (i) the development of quantitative measurements for nano-scale field measurements and (ii) the use of MFM for the characterization of magnetic nanostructures and nano devices.
Quantum calibrated magnetic force microscopy 12/2021
We report the quantum calibration of a magnetic force microscope (MFM) by measuring the two-dimensional magnetic stray-field distribution of the MFM tip using a single nitrogen vacancy (NV) center in diamond
