Popis: Electron spins in diamond allow magnetometry with high sensitivity, but the bandwidth in the microwave regime is limited to a narrow band around their resonance frequency. Here, the authors solve this problem by coupling the spins to a thin film of yttrium iron garnet, exploiting the non-linear spin-wave dynamics of the magnet.
