Electrons carry both an electric charge and a tiny magnetic property called spin. Controlling how spin and charge interact underlies much of modern technology, from magnetic sensors to future quantum devices.

What they work on
- Make magnetic nanoparticles with set composition and magnetic phase by colloidal synthesis, assemble them into composites, and correlate magnetometry of single particles with the magnetoresistance of the solids.
- Establish quantitative links between interparticle interaction strength, single-particle magnetic anisotropy and particle volume and the magnetoresistance response, starting with ferrites.
- Extend nanoparticle composites to higher-performing magnetic materials to create magnetoresistive systems with tunable field sensitivity and pseudo-spin-valve behavior for sensing.
- Use erbium–cyclooctatetraene units, whose magnetic moment has a predictable direction, as building blocks to design through-space dipolar interactions between lanthanide molecules.
- Vary the symmetry, angles and dimensionality of linked erbium complexes to test how dipolar coupling controls spin dynamics and relaxation, combining synthesis with theory and computation.
More about the research
The research in these grants builds magnetic materials from the bottom up, from carefully made nanoparticles or single molecules. The goal is to link their structure directly to their magnetic behavior.
Why it matters
Simpler, tunable magnetoresistive materials made from low-cost nanoparticles could lead to magnetic sensors with adjustable sensitivity. Design rules for coupling magnetic molecules could improve models of how spins relax. They could also offer new routes to entangled quantum states for quantum information science. Openly shared data will let other researchers test their own theories of spin transport.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
