Fast, cheap, and scalable magnetic tracker with an array of magnetoresistors
Valerio Biancalana, Roberto Cecchi, Piero Chessa +3
We present the hardware of a cheap multi-sensor magnetometric setup where a relatively large set of magnetic field components is measured in several positions by calibrated magneto…
Ferromagnetic contamination of Ultra-Low-Field-NMR sample containers. Quantification of the problem and possible solutions
Giuseppe Bevilacqua, Valerio Biancalana, Marco Consumi +4
The presence of a weak remanence in Ultra-Low-Field (ULF) NMR sample containers is investigated on the basis of proton precession. The high-sensitivity magnetometer used for the NM…
Harmonic fine tuning and triaxial spatial anisotropy of dressed atomic spins
Giuseppe Bevilacqua, Valerio Biancalana, Antonio Vigilante +2
The addition of a weak oscillating field modifying strongly dressed spins enhances and enriches the system quantum dynamics. Through low-order harmonic mixing the bichromatic drivi…
Fast switching coil system for sample premagnetization in an unshielded ultra-low-field Nuclear Magnetic Resonance experiment
Valerio Biancalana, Roberto Cecchi, Leonardo Stiaccini +1
We present a system developed to premagnetize liquid samples in an ultra-low-field Nuclear Magnetic Resonance (NMR) experiment. Liquid samples of a few milliliter are exposed to a…
