Scanning magnetic field microscope with a diamond single-spin sensor
C. L. Degen
We describe a scanning device where a single spin is used as an ultrasensitive, nanoscale magnetic field sensor. As this "probe spin" we consider a single nitrogen-vacancy defect c…
An off-board quantum point contact as a sensitive detector of cantilever motion
M. Poggio, M. P. Jura, C. L. Degen +4
Recent advances in the fabrication of microelectromechanical systems (MEMS) and their evolution into nanoelectromechanical systems (NEMS) have allowed researchers to measure extrem…
Nuclear spin relaxation induced by a mechanical resonator
C. L. Degen, M. Poggio, H. J. Mamin +1
We report on measurements of the spin lifetime of nuclear spins strongly coupled to a micromechanical cantilever as used in magnetic resonance force microscopy. We find that the ro…
Nuclear magnetic resonance force microscopy with a microwire rf source
M. Poggio, C. L. Degen, C. T. Rettner +2
We use a 1.0-um-wide patterned Cu wire with an integrated nanomagnetic tip to measure the statistical nuclear polarization of 19F in CaF2 by magnetic resonance force microscopy (MR…
Feedback cooling of a cantilever's fundamental mode below 5 mK
M. Poggio, C. L. Degen, H. J. Mamin +1
We cool the fundamental mechanical mode of an ultrasoft silicon cantilever from a base temperature of 2.2 K to 2.9 +/- 0.3 mK using active optomechanical feedback. The lowest obser…
