We have used polarized and unpolarized neutron diffraction to determine the spatial distribution of the magnetization density induced by a magnetic field of 9 T in the tetragonal phase of K0.8Fe1.6Se2. The maximum entropy reconstruction shows clearly that most of the magnetization is confined to the region around the iron atoms whereas there is no significant magnetization associated with either Se or K atoms. The distribution of magnetization around the Fe atom is slightly nonspherical with a…

Unwinding of a Skyrmion Lattice by Magnetic Monopoles
TLDR
This study revealed that skyrmions vanish by a coalescence, forming elongated structures, and numerical simulations showed that changes of topology are controlled by singular magnetic point defects.
