By now, spintronics is an established field of condensed matter physics and has become an active branch in the sensor and the microelectronics industry. The discovery of the Giant Magnetoresistance in 1988 by Pr. A. Fert, who was awarded the 2007 Nobel Prize in Physics together with Pr. P. Grünberg, marks the birth of spintronics. After three decades of research, the field of spintronics still presents vivid dynamics at the fundamental level and in applications.
As such, new concepts like topological spin textures have recently arisen in the community, which could bring disruptive solutions in information-communication technologies, neuromorphic electronics, etc. The development and access to user-friendly advanced characterization tools in nanomagnetism is a key requirement to study new magnetic phenomena. In this context, magnetic force microscopy (MFM) is a unique characterization technique that can image even weak magnetic signals from nanometer scale spin textures very efficiently. MFM is an atomic force microscopy method, in which a magnetized tip-cantilever system probes the magnetic properties of a surface with a nanoscale resolution. This real-space, high-resolution visualization of magnetic structures offers valuable insights for research and application of spintronics.
In this talk I’ll present you, from the Engineer point of view, the contribution of MFM in various experimental configurations to the undergoing research at UMPhy on ferromagnetic and antiferromagnetic skyrmions.

The theoretical introduction on (High Vacuum) MFM will be done by Ilka Hermes, Principle Scientist at Park Systems Europe.

This is a pre-recorded webinar. All questions asked during the session will be answered via email.
