Direct, nonvolatile, and reversible control of nanomagnetism in solid‐state ferromagnetic thin films is achieved by controlling the chemical composition of the film through field‐driven ion redistribution. The electric field‐driven de‐intercalation/intercalation of lithium ions can result in ≈100% modulation of the magnetization and drives domain wall motion over ≈100 nm. High‐speed and multilevel magnetic information storage is further demonstrated.
