Description
Hongzhan Ju and co-authors study gadolinium doping in permalloy films for spin electronics in a 2026 physics report. Permalloy damps magnetic motion very weakly, which saves power but limits fast-switching devices that need stronger braking.
Films pairing platinum with permalloy-gadolinium mixes were made by sputtering and probed with spin-torque resonance tests. Adding gadolinium raised damping step by step, peaking at a mid-level dose with more than double the pure value. Charge-to-spin conversion also improved sharply, reaching its best level at a higher dose. Rare earth tuning thus gives device designers two useful dials at once.
