30 Jun WEBINAR | Magnetic Force Microscopy – what you should know about it!
Groot-Ammers | June 30th, 2022
Magnetic Force Microscopy (MFM) is a well-known non-contact scanning probe (SPM) technique established for more than 35 years by now, that is capable of mapping near-surface magnetic textures and structures down to the 10-nm-spatial resolution. MFM becomes an indispensable and complementary tool in modern-type material analysis, especially when focusing for instance on topological and low-dimensional systems.

In this webinar the focus will be on how we can separate magnetic information by MFM, from other (local) signals, especially also shedding light on the different SPM “channels” that might deliver the wanted magnetic information, i.e. as a frequency shift, as a net dissipation signal, or even as an electrostatic signal, just to mention the most popular ones. Careful analysis of these signals even allows to differentiate Néel-type from Bloch-type domain walls (DWs), hence paving the way for the quantitative investigation of magnetic skyrmions (SKYs) and antiskyrmions. I will finish this webinar by emphasizing on the indispensable need of MFM for the nanosciences, in that MFM has the power to readily prove that many estimates on magnetic textures, deduced from macroscopic measurements such as Anomalous and Topological Hall transport, are in fact wrong and heavily overinterpreted.
