Tunable magnetization damping in transition metal ternary alloys
Tunable magnetization damping in transition metal ternary alloys
We show that magnetization damping in Permalloy, Ni80Fe20, can be enhanced sufficiently to reduce postswitching magnetization precession to an acceptable level by alloying with the transition metal Os (osmium). The damping increases monotonically upon raising the Os concentration in Permalloy, at least up to 9% of Os. Other effects of …
