Broadband microwave detection using electron spins in a hybrid diamond-magnet sensor chip

Autor: Joris J. Carmiggelt, Iacopo Bertelli, Roland W. Mulder, Annick Teepe, Mehrdad Elyasi, Brecht G. Simon, Gerrit E. W. Bauer, Yaroslav M. Blanter, Toeno van der Sar

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-6 (2023)

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 y

Spin waves in magnetic insulators are low-damping signal carriers that can enable a new generation of spintronic devices. The excitation, control, and detection of spin waves by metal electrodes is crucial for interfacing these devices to electrical

Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of coherent sp

Magnetic imaging and statistical analysis of the metamagnetic phase transition of FeRh with electron spins in diamond

Autor: Rajasekhar Medapalli, D. Afanasiev, Toeno van der Sar, Brecht G. Simon, Iacopo Bertelli, Guillermo Nava Antonio

Publikováno v: Journal of Applied Physics, 129(22)

Magnetic imaging based on nitrogen-vacancy (NV) centers in diamond has emerged as a powerful tool for probing magnetic phenomena in fields ranging from biology to physics. A key strength of NV sensing is its local-probe nature, enabling high-resoluti

We present a theory for quantum impurity relaxometry of magnons in thin films, exhibiting quantitative agreement with recent experiments without needing arbitrary scale factors used in theoretical models thus far. Our theory reveals that chiral coupl

Spins in diamond enable quantitative, phase-sensitive magnetic resonance imaging of coherent spin waves in thin-film magnets.
Spin waves—the elementary excitations of magnetic materials—are prime candidate signal carriers for low-dissipation

Tribology Transactions, 61, 705-712

It has been known for decades that high contact load in bearings leads to fatigue alterations of subsurface material, which can be optically visualized on etched samples. In the literature, these a...
