Working Group 2.52


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.

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.
