14 GHz longitudinally detected electron spin resonance using microHall sensors

Radivoje Popovic, Schahrazede-Lila Mouaziz, Malika Bouterfas

In this work we developed a home-made LOngitudinally Detected Electron Spin Resonance (LODESR) spectrometer based on a microsize Hall sensor. A coplanar waveguide (CPW)-resonator is used to induce microwave-excitation on the sample at 14 GHz. We used InSb ...

Two-dimensional magnetic resonance force microscopy using full-volume Fourier and Hadamard encoding

Giovanni Boero, Jürgen Brugger, Schahrazede-Lila Mouaziz

A rapid acquisition method for two-dimensional (2D) magnetic resonance force microscopy images is described. Spatial resolution is based on gradients in the static magnetic field B0 and in the applied radiofrequency field B1. Hadamard- and Fourier-encoding ...

Direct observation of nuclear spin diffusion in real space

Giovanni Boero, Jürgen Brugger, Schahrazede-Lila Mouaziz

Images directly visualizing the spatial spin-diffusion process are reported. The measurements were performed using a magnetic resonance force microscope. The field gradient associated with the forcedetection experiment is large enough to affect the spin dy ...

Integrated Nickel Micro-Nano-Hall Sensors on SU-8 Cantilevers for Scanning Hall Probe Microscopy

Radivoje Popovic, Giovanni Boero, Christian Santschi, Chantal Imboden, Jürgen Brugger, Schahrazede-Lila Mouaziz, Oscar Vazquez Mena

We report the fabrication and characterization of nickel Hall sensors integrated on SU-8 cantilevers. Sensors having active area down to 1x1 μm 2 show a magnetic field resolution better than 1μT/Hz 1/2 in the thermal noise frequency range. The fabricated d ...
