Nano-layer of Ruthenium Stabilizes Magnetic Sensors

Caption

A thin layer of ruthenium (green in the cartoon) improves magnetic sensors by modulating interactions between a nickel/iron film (blue) that responds to external magnetic fields and an iridium/manganese stabilizer film (pink). The ruthenium aligns its electron spins, indicated by arrows, with the nearest layers in both films.
