United KingdomResearchers have achieved precise control over the 'chirality' (or handedness) of a metallic helimagnet, which could lead to advancements in high-density data storage technologies. Magnetic storage devices currently face challenges with miniaturization due to interference between magnetic components. This study demonstrates that by applying both a magnetic field and an electric current, the spiral arrangement of atomic magnetic moments in a helimagnet can be uniformly controlled to either a left- or right-handed configuration. The team used spin-polarized neutron scattering to directly observe the microscopic changes in chirality, confirming the effectiveness of their method. This breakthrough could allow for more efficient and compact memory storage solutions.
