"greater efficiency/ higher density than horizontal alignment... ion beam magnetic engraving imprints magnetic nanostrips onto iron-vanadium alloy thin film... ion beam locally orders atoms into crystal lattice, making bombarded areas ferromagnetic... reduced nanostrip widths to 25 nm, forcing magnetic moments to stand out vertically from surface... increased data storage density, increased efficiency especially in spintronics, enhanced sensitivity, cost-effective... magnetic storage, sensors, spin-based quantum computing"
