Asylum AFMs Study Materials Under Variable Applied Magnetic Fields

Magnetic nanostructures are a vibrant field of research, not only for data storage but also for next-generation logic elements. Learn how magnetic force microscopy (MFM) under applied magnetic fields is enabling new insights.

Learn about Asylum AFM tools for MFM:

  • Operating principles of magnetic force microscopy
  • Capabilities of the Variable Field Module for both in-plane and out-of-plane magnetic fields
  • Automation of MFM measurements using scripting to capture domain evolution as a function of the applied magnetic field strength

These capabilities are illustrated by two case studies:

  • Systematic study of domain structure in a Co/Ni thin film that exhibits perpendicular magnetic anisotropy (PMA)
  • Direct observation of magnetic skyrmions under applied fields, a feat previously only possible with costly, time-consuming scanning x-ray transmission microscopy (STXM) at a synchrotron facility
