|Researchers at Purdue University have developed a new method for hybrid sensing of electric fields using quantum spin defects (QSD). Currently, electric sensing for small electric field sensitivity (about 1000 V cm^-1) are possible, but dynamic range remains uncertain. The new highly sensitive technique created by Purdue researchers can detect small changes in electric fields by optimizing coupling excitations in nanomagnets with QSD, including those of nitrogen-vacancy centers found in nanodiamonds offering measurable signals that orders of magnitude higher in resolution. This can be implemented in quantum spintronics devices, single spin probes of multiferroic order, and NV-sensing of electric fields.
-Enhanced Dynamic Range
-Improved Electric Field Sensing
-Nitrogen-Vacancy Sensing of Electric Fields
-Single Spin Probes of Multiferroic Order
Technology Validation: The ferroelectric polarization changes nitrogen-vacancy spin relaxation rates by 400%, improving the patterning of the ferromagnetics by three orders of magnitude.
