Electromagnetic field mapping

Current research topics include the study of: 

  • Projected electrostatic potentials and charge densities in needle-shaped specimens;
  • Magnetic fields of skyrmions in chiral magnets and thin films;
  • Complementary measurements of in-plane and out-of-plane magnetic signals using electron magnetic circular dichroism (EMCD) and off-axis electron holography;
  • Magnetic microstructures and domain wall widths in soft and hard magnets and magnetic high entropy alloys; 
  • Ultrafast electron tomographic holography;
  • Double-exposure electron holography;
  • Microwave-assisted high frequency dynamical processes;
  • Strain measurements in functional oxides using dark-field electron holography;
  • Tunable phase plates and electron vortex beam generators;
  • Orbital angular momentum of the electron wavefront.
