Direct imaging of magnetotransport at graphene-metal interfaces with a single-spin quantum sensor
C. Ding, M. L. Palm, K. Kohli +3
Magnetotransport underlines many important phenomena in condensed matter physics, such as the Hall effect and magnetoresistance (MR) effect. Thus far, most magnetotransport studies…
Minimizing sensor-sample distances in scanning nitrogen-vacancy magnetometry
Zhewen Xu, Marius L. Palm, William S. Huxter +10
Scanning magnetometry with nitrogen-vacancy (NV) centers in diamond has led to significant advances in the sensitive imaging of magnetic systems. The spatial resolution of the tech…
Observation of current whirlpools in graphene at room temperature
Marius L. Palm, Chaoxin Ding, William S. Huxter +3
Electron-electron interactions in high-mobility conductors can give rise to transport signatures resembling those described by classical hydrodynamics. Using a nanoscale scanning m…
Scanning nitrogen-vacancy magnetometry down to 350mK
Patrick J. Scheidegger, Simon Diesch, Marius L. Palm +1
We report on the implementation of a scanning nitrogen-vacancy (NV) magnetometer in a dry dilution refrigerator. Using pulsed optically detected magnetic resonance combined with ef…
Scanning gradiometry with a single spin quantum magnetometer
William S. Huxter, Marius L. Palm, Miranda L. Davis +4
Here, we demonstrate a gradiometry technique that significantly enhances the measurement sensitivity of such static fields, leading to new opportunities in the imaging of weakly ma…
Imaging of sub-A currents in bilayer graphene using a scanning diamond magnetometer
M. L. Palm, W. S. Huxter, P. Welter +9
Nanoscale electronic transport gives rise to a number of intriguing physical phenomena that are accompanied by distinct spatial patterns of current flow. Here, we report on sensiti…
