Proto-IRG: Spin Textures in Chiral Magnetic Materials

  • Experimental evidence in MBE-grown FeGe thin films for “chiral bobbers”, topological spin texture that exist near an interface.
  • Theoretical modeling  predicts stable chiral bobbers in materials with both bulk and interfacial DMI.
  • Lorentz TEM imaging of skyrmions in FeGe thinned crystals
  • Topological Hall effect measurements of skyrmions in FeGe thin films and novel oxide heterostructures of SrIrO3/SrRuO3.
  • Development of microwave absorption spectroscopy to probe skyrmion materials.
