| Outline of Final Research Achievements |
The purpose of this study was to observe nanometer-scale vortex-like magnetic structures called magnetic skyrmions by means of resonant soft x-ray small-angle scattering. Resonant soft x-ray scattering is an element-selective method that can observe the magnetic state by using soft x-rays of energy corresponding to the absorption edge of the target element. Using this method, we observed how magnetic skyrmions are generated and annihilated by an application of external electric field, and how magnetic structures change from magnetic skyrmions to magnetic chiral soliton lattices by tensile strain from the substrate. We also succeeded in reconstructing a real space image element-selectively with a spatial resolution of several tens of nanometers by a phase retrieval algorithm from a diffraction pattern obtained using coherent soft x-rays.
