MFM for Optimization of Sintered Magnets
MFM image of a NdFeB sintered magnet with the nominal c-axis orientation perpendicular to the surface. The sample is in the remanent state but some surface
grains show already magnetization reversal. High resolution imaging allows deeper
insights into the magnetic reversal mechanism and the optimization of magnetic
properties. Image size is 30x30µm².

Piezo Response Force image on BFO
This image shows the attocube logo electrically written into a BaFeO3 substrate next
to natural domains of the sample. The data were taken at 4K in piezo response force
mode using an attoAFM/MFM I. Image size is 5x5µm².

Helimagnetic Phase of Fe0.5Co0.5Si
1µm
Real space imaging of exotic magnetic phases provides a level of understanding
that cannot be achieved with indirect techniques. The figure on the left shows
one of the first observations of a helimagnetic phase using the attoMFM I. The
periodicity of the stripes is around 100 nm. This phase is of particular interest
because of its proximity to a skyrmion phase. Skyrmions are exotic magnetic
excitations, studied extensively because of their potential use in spintronic
applications. The measurement was performed on a FeCo0.5Si0.5 sample at 4 K
using an attoMFM I in attocube application labs.
