Deformation of Skyrmion Crystal under Strain and under Driving Current
Manipulation of spin textures has been attracting a broad interest
from the viewpoints of both fundamental physics and applications over
decades. In particular, the control magnetic skyrmions is one of the
hottest topics. In the first part of my talk, I will talk about the
static deformation of skyrmion crystals under uniaxial strain revealed
by the Lorentz TEM observation. This experimental result is analyzed
by the model with an anisotropic Dzyaloshinskii-Moriya interaction,
which shows a good agreement with the experiment. In the next part, I
will discuss the dynamical deformation of skyrmion crystals under a
driving current and the corresponding suppression of the Bragg peak
intensities, which we expect to be measured by neutron scattering
experiments.
