Journal ArticleDOI
Off-resonant manipulation of spins in diamond via precessing magnetization of a proximal ferromagnet
Christopher Wolfe,Vidya P. Bhallamudi,Hailong Wang,Chunhui Du,Sergei A. Manuilov,Richelle M. Teeling-Smith,Andrew J. Berger,Rohan Adur,Fengyuan Yang,P. C. Hammel +9 more
TL;DR: In this paper, the spin state of an Larmor can be modified nonresonantly (i.e. at frequencies far from the Larmor frequencies) via coupling to the dynamic magnetization of a ferromagnet.
Journal ArticleDOI
Electron Paramagnetic Resonance of a Single NV Nanodiamond Attached to an Individual Biomolecule
Richelle M. Teeling-Smith,Young Woo Jung,Nicolas Scozzaro,Jeremy Cardellino,Isaac Rampersaud,Justin A. North,Marek Simon,Vidya P. Bhallamudi,Arfaan A. Rampersaud,Ezekiel Johnston-Halperin,Michael G. Poirier,P. Chris Hammel +11 more
TL;DR: This demonstration of EPR spectroscopy of a single nanodiamond-labeled DNA provides the foundation for the development of single-molecule magnetic resonance studies of complex biomolecular systems.
Journal ArticleDOI
Voltage-driven, local, and efficient excitation of nitrogen-vacancy centers in diamond.
Dominic Labanowski,Vidya P. Bhallamudi,Qiaochu Guo,Carola M. Purser,Brendan McCullian,P. Chris Hammel,Sayeef Salahuddin +6 more
TL;DR: This work demonstrates a new pathway that combine acoustics and magnonics that enables highly energy-efficient and local excitation of NV centers without the need for any external RF excitation and, thus, could lead to completely integrated, on-chip, atomic sensors.
Journal ArticleDOI
Broadband multi-magnon relaxometry using a quantum spin sensor for high frequency ferromagnetic dynamics sensing.
Brendan McCullian,Ahmed M. Thabt,Benjamin Gray,Alex L. Melendez,Michael S. Wolf,Vladimir L. Safonov,Denis V. Pelekhov,Vidya P. Bhallamudi,Michael R. Page,P. Chris Hammel +9 more
TL;DR: It is found that the NVs are relaxed by the driven spinwave instability despite the absence of any individual NV-resonant magnons, suggesting that multiple magnons participate in creating magnetic field noise below the ferromagnetic gap frequency which causes NV spin relaxation.
Journal ArticleDOI
Spatially resolved detection of complex ferromagnetic dynamics using optically detected nitrogen-vacancy spins
C. S. Wolfe,Sergei A. Manuilov,Carola M. Purser,Richelle M. Teeling-Smith,Carsten Dubs,P. C. Hammel,Vidya P. Bhallamudi +6 more
TL;DR: In this paper, the authors demonstrate optical detection of a broad spectrum of ferromagnetic excitations using nitrogen-vacancy (NV) centers in an ensemble of nanodiamonds.
