Magnetostrictive Materials for Enhanced Sensors and Electronic Components

Executive Summary

The goal of this project is to explore a burgeoning class of magnetostrictive materials for use in electromagnetic sensors and other devices, with a particular focus on developing feedstock suitable for advanced manufacturing processes. This research could have broad impact across the Department of Energy’s mission space, including energy grid modernization and nuclear materials detection.
