抜粋

Magnetostrictive materials have attracted attention as materials for energy harvesting such as vibration power generation for Internet of Things (IoT). Fe-Co alloys have been focused on since the alloys have remarkable magnetic and mechanical properties. In this work, we evaluated the effect of heat treatment on the magnetic and magnetostrictive properties of rolled Fe-Co magnetostrictive films with Cr and Mo addition as bcc stabilizing elements to clarify. It was shown that the coercivity and the residual magnetism of the annealed specimens increase with the increase of the additive element quantity. This result indicates an increase in the amount of vibration power generation due to the Villari effect.
