DESCRIPTION:Magnetic skyrmions are localized spin textures in-which the mag
 netic moments curl into a continuous\, coplanar loop\, bounded on its outs
 ide perimeter and core by moments in the out-of-plane direction. This very
  specific configuration provides a non-trivial topology and quasiparticle 
 qualities\, including skyrmion kinetics and dynamic modes. Hybrid skyrmion
 s have shown the largest stability envelope\, which includes room temperat
 ure and zero magnetic field\, making them attractive for skyrmion spintron
 ic devices. In the first part of this talk I will present the basic usage 
 of small angle neutron scattering (SANS) in preparing an ordered lattice o
 f hybrid skyrmions. Then\, using grazing incidence SANS and neutron reflec
 tometry\, we elucidate the 3D structure of the skyrmions – which is impo
 rtant for both the topology and stability. In the third part\, we use SANS
  as an in-situ probe of the gigahertz skyrmion dynamics and discover a spi
 n wave fractal network generated by collective interference.\n\nCo-sponsor
