Some magnetic materials change shape slightly when placed in a magnetic field, a property called magnetostriction. Materials that stretch a lot under a small field, and reverse cleanly, are useful in sensors, actuators and underwater communication devices.

What they work on
- Test whether two-phase nanostructures break the spin-orbit coupling link to produce large magnetostriction with weak anisotropy in Fe-Ga-based alloys containing aluminum or germanium.
- Determine the nanostructures of these alloys and of nano-chessboard cobalt ferrite in bulk and thin-film forms, using X-ray and neutron diffraction with magnetic measurements.
- Observe how nanostructure governs magnetostriction using transmission electron microscopy of samples placed under mechanical stress.
More about the research
Achieving a large shape change under small fields is unusual. This project asks what structure at the nanometer scale makes it possible.
Why it matters
Materials that change shape strongly under small magnetic fields are needed in sensors, actuators and underwater communication devices. Understanding how nanostructure produces this behavior could guide the design of better magnetostrictive alloys and ceramics for these technologies.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
