Wide Temperature Range Biskyrmion Magnetic Nanodomains in MnNiGa Study by Small Angle Neutron Scattering

DOI

Magnetic skyrmions are topological vortex-like spin objects that were recently discovered in bulk chiral magnetic materials. Last year we discovered super stable magnetic biskyrmions 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. Aiming for map the biskyrmions in reciprocal space and study the biskyrmion lattice kinetics as a function of magnetic field at different temperatures, we propose to perform SANS experiment in MnNiGa polycrystalline sample and also the new synthesized cylindrical-shaped single-crystalline MnNiGa sample at temperature range of 10 - 320 K. Study the magnetic biskyrmions lattice kinetics as a function of magnetic field at different temperatures is essential to understand the topological properties of biskyrmion.
