    abstract = {Magneto-ionics, an emerging approach to manipulate magnetism
               that relies on voltage-driven ion motion, holds the promise to
               boost energy efficiency in information technologies such as
               spintronic devices or future non-von Neumann computing
               architectures. For this purpose, stability, reversibility,
               endurance, and ion motion rates need to be synergistically
               optimized. Among various ions, nitrogen has demonstrated superior
               magneto-ionic performance compared to classical species such as
               oxygen or lithium. Here, we show that ternary Co1−xFexN
               compound exhibits an unprecedented nitrogen magneto-ionic
               response. Partial substitution of Co by Fe in binary CoN is shown
               to be favorable in terms of generated magnetization, cyclability
               and ion motion rates. Specifically, the Co0.35Fe0.65N films
               exhibit an induced saturation magnetization of 1,500 emu/cm3, a
               magneto-ionic rate of 35.5 emu/(cm3·s) and endurance exceeding
               103 cycles. These values significantly surpass those of other
               existing nitride and oxide systems. This improvement can be
               attributed to the larger saturation magnetization of Co0.35Fe0.65
               compared to individual Co and Fe, the nature and size of
               structural defects in as-grown films of different composition,
               and the dissimilar formation energies of Fe and Co with N in the
               various developed crystallographic structures.},
