Microwave-Free Nuclear Magnetic Resonance at Molecular Scales
James D. A. Wood, Jean-Philippe Tetienne, David A. Broadway +4
The implementation of nuclear magnetic resonance (NMR) at the nanoscale is a major challenge, as conventional systems require relatively large ensembles of spins and limit resoluti…
Quantum imaging of current flow in graphene
Jean-Philippe Tetienne, Nikolai Dontschuk, David A. Broadway +3
Since its first isolation in 2004, graphene has been found to host a plethora of unusual electronic transport phenomena, making it a fascinating system for fundamental studies in c…
Spin dynamics of diamond nitrogen-vacancy centres at the ground state level anti-crossing and all-optical low frequency magnetic field sensing
David A. Broadway, James D. A. Wood, Liam T. Hall +5
We investigate the photo-induced spin dynamics of single nitrogen-vacancy (NV) centres in diamond near the electronic ground state level anti-crossing (GSLAC), which occurs at an a…
Direct measurement of interfacial Dzyaloshinskii-Moriya interaction in X/CoFeB/MgO heterostructures with a scanning-NV magnetometer
I. Gross, L. J. Martínez, J. -P. Tetienne +11
The Dzyaloshinskii-Moriya Interaction (DMI) has recently attracted considerable interest owing to its fundamental role in the stabilization of chiral spin textures in ultrathin fer…
Wide-band, nanoscale magnetic resonance spectroscopy using quantum relaxation of a single spin in diamond
James D. A. Wood, David A. Broadway, Liam T. Hall +4
We demonstrate a wide-band all-optical method of nanoscale magnetic resonance (MR) spectroscopy under ambient conditions. Our method relies on cross-relaxation between a probe spin…
