Dynamical process of helical-biskyrmion transformation of hexagonal magnet MnNiGa probed by SANS

Abstract: Magnetic skyrmions are vortex-like, magnetic-spin objects that were lately discovered in bulk chiral magnetic materials. Recently, we discovered super stable magnetic biskyrmions (or skyrmion molecules) which is a new type of skyrmmion formed by two skyrmions of opposite spin helicities, in an extremely wide temperature range of 10 K to 350 K in MnNiGa sample by the combination of in-situ Lorentz transmission electron microscopy images and magnetoresistivity and topological Hall effect measurements (submitted to Adv. Mater.). However, the magnetic biskyrmions in this MnNiGa material have not been determined experimentally by neutron scattering and their physical origin also remains unclear. Aim to solve these problems, here we propose a SANS study of the magnetic biskyrmions lattice kinetics as a function of magnetic field at different temperatures.
