Biskyrmion Magnetic Nanodomains in the MnNiGa single-crystalline Study by Small Angle Neutron Scattering

Abstract: Magnetic skyrmions are topological vortex-like spin objects that were recently discovered in bulk chiral magnetic materials. Several months ago we discovered super stable magnetic biskyrmions (or skyrmion molecules) which is a new type of skyrmion formed by two bound skyrmions with oppositely magnetic helicities, in an extremely wide temperature range of 100 - 340 K in MnNiGa sample by in-situ real-space Lorentz transmission electron microscopy. Considering that the biskyrmion size is around 100 nm and its lattice ~ 400 nm, SANS is the ideal tool for studying its properties. We propose to perform SANS experiment in single-crystalline MnNiGa sample to characterize the expected biskyrmion sixfold lattice. Study the magnetic biskyrmions lattice kinetics as a function of magnetic field at different temperatures is essential to understand the topological properties of biskyrmion.
