Feasibility of imaging using Boltzmann polarization in nuclear Magnetic Resonance Force Microscopy
Martin de Wit, Gesa Welker, Jelmer Wagenaar +2
We report on Magnetic Resonance Force Microscopy measurements of the Boltzmann polarization of the nuclear spins in copper by detecting the frequency shift of a soft cantilever. We…
A method for mechanical generation of radio frequency fields in nuclear magnetic resonance force microscopy
J. J. T. Wagenaar, A. M. J. den Haan, R. J. Donkersloot +4
We present an innovative method for magnetic resonance force microscopy (MRFM) with ultra-low dissipation, by using the higher modes of the mechanical detector as radio frequency (…
Observing "Quantized" Conductance Steps in Silver Sulfide: Two Parallel Resistive Switching Mechanisms
J. J. T. Wagenaar, M. Morales-Masis, J. M. van Ruitenbeek
We demonstrate that it is possible to distinguish two conductance switching mechanisms in silver sulfide devices at room temperature. Experiments were performed using a AgS thi…
Probing the Nuclear Spin-Lattice Relaxation Time at the Nanoscale
J. J. T. Wagenaar, A. M. J. den Haan, J. M. de Voogd +9
Nuclear spin-lattice relaxation times are measured on copper using magnetic resonance force microscopy performed at temperatures down to 42 mK. The low temperature is verified by c…
Spin-mediated dissipation and frequency shifts of a cantilever at milliKelvin temperatures
A. M. J. den Haan, J. J. T. Wagenaar, J. M. de Voogd +2
We measure the dissipation and frequency shift of a magnetically coupled cantilever in the vicinity of a silicon chip, down to mK. The dissipation and frequency shift originat…
Dissipation and resonance frequency shift of a resonator magnetically coupled to a semiclassical spin
J. M. de Voogd, J. J. T. Wagenaar, T. H. Oosterkamp
We calculate the change of the properties of a resonator, when coupled to a semiclassical spin by means of the magnetic field. Starting with the Lagrangian of the complete system,…
Local control of single atom magneto-crystalline anisotropy
B. Bryant, A. Spinelli, J. J. T. Wagenaar +2
Individual Fe atoms on a Cu2N/Cu(100) surface exhibit strong magnetic anisotropy due to the crystal field. Using atom manipulation in a low-temperature STM we demonstrate that the…
Detection and control of individual nuclear spins using a weakly coupled electron spin
T. H. Taminiau, J. J. T. Wagenaar, T. van der Sar +3
We experimentally isolate, characterize and coherently control up to six individual nuclear spins that are weakly coupled to an electron spin in diamond. Our method employs multi-p…
