Demonstration of Weak-Link Physics in the Dynamical Response of Transition-Edge Sensors
Marios Kounalakis, Luciano Gottardi, Martin de Wit +1
We theoretically predict and experimentally observe the onset of weak-link physics in the dynamical response of transition edge sensors (TES). We develop a theoretical framework ba…
Increased muon field at surface and substrate interface of palladium thin films
Gesa Welker, Martin de Wit, Tjerk H. Oosterkamp +4
We performed depth-dependent low-energy muon spin spectroscopy (SR) studies on three palladium 100 nm thin films, both undoped and doped with 170 ppm of iron. Muons implanted in…
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…
Density and of surface and bulk spins in diamond in high magnetic field gradients
Martin de Wit, Gesa Welker, Marc de Voogd +1
We report on surface and bulk spin density measurements of diamond, using ultra-sensitive magnetic force microscopy with magnetic field gradients up to 0.5 T/m. At temperatures…
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 (…
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…
