An effective, low‐temperature and readily available electrochemical method for tuning the operation temperature of LaFe 13‐x Si x ‐type alloys is demonstrated. Electrolytically hydrided materials have the same high level magnetic properties as in high temperature gas‐phase processed materials and offer an advantage of higher hydrogen absorption rate in the ferromagnetic state.
