Generating biskyrmions in a rare earth magnet

Phys.org  September 16, 2023 The low stability of most magnetic skyrmions leads to either a narrow temperature range in which they can exist, a low density of skyrmions, or the need for an external magnetic field, which greatly limits their wide application. An international team of researchers (USA – NIST, Japan, South Korea) has reported real-space imaging of a two-dimensional skyrmion lattice in a thin film of Fe0.5Co0.5Si using Lorentz transmission electron microscopy. With a magnetic field of 50–70 mT applied normal to the film, they observed skyrmions in the form of a hexagonal arrangement of swirling spin textures, with a […]
