Spintronics: Generation of magnetic biskyrmions by electric current Electric current can generate and control the density of magnetic biskyrmions in a centrosymmetric MnNiGa alloy at room temperature. Skyrmions are chiral spin textures whose spins point in all directions wrapping a sphere. making them topological in nature. Topological protection. https://foldlyers.shop/product-category/vacuum-sealing/
