Helium-Ion Beam Systems for Thin Magnetic Films

Spin-Ion Technologies Helium-S

Spin-Ion Technology offers ultra-compact Helium-ion beam process technology to enhance the magnetic properties of thin films at the atomic scale. For more than 20 years, Spin-Ion’s research team has been developing a patented process solution to treat magnetic materials to enhance their performance, reducing manufacturing costs and improving yield for both HDD and MRAM applications. This process is based on post-growth He+ ion irradiation to tailor the magnetic properties of thin magnetic films at the atomic scale and improve their performances. The utilization of light ions provides the precise control of inter-atomic displacements through the low energy transfer. The key feature of the technology is the precise control of magnetic properties including: perpendicular magnetic anisotropy, ferromagnetic order, damping, Dzyaloshinskii-Moriya Interaction, and domain wall/skyrmions dynamics or SOT switching. Spin-Ion's technology has been developed to deliver dedicated tools to customers working in nano-magnetism and spintronics.
