  • NANODEVICE, METHOD OF MAKING THE SAME, AND METHOD OF USING THE SAME
    Publication number: 20240045002
    Abstract: A nanodevice provides for electric-field control of magnon-QSD interactions. The nanodevice includes a ferroelectric substrate, a ferromagnetic material disposed over the ferroelectric substrate, and a nanodiamond including an ensemble of nitrogen-vacancy (NV) spins, each NV magnetically interfacing with the ferromagnetic material. An electric field is measured by applying a voltage across the ferroelectric substrate and the ferromagnetic material, changing a magnon excitation spectrum of the ferromagnetic material with respect to an electron spin resonance frequency of the ensemble of NV spins, and measuring a relaxation rate of the ensemble of NV spins.
    Type: Application
    Filed: October 13, 2023
    Publication date: February 8, 2024
    Applicant: Purdue Research Foundation
