A room-temperature alternating current susceptometer - Data analysis, calibration, and test
M. Alderighi, G. Bevilacqua, V. Biancalana +3
An AC susceptometer operating in the range of 10 Hz to 100 kHz and at room temperature is designed, built, calibrated and used to characterize the magnetic behaviour of coated magn…
Larmor frequency dressing by an anharmonic transverse magnetic field
G. Bevilacqua, V. Biancalana, Y. Dancheva +1
We present a theoretical and experimental study of spin precession in the presence of both a static and an orthogonal oscillating magnetic field, which is nonresonant, not harmonic…
A new class of sum rules for products of Bessel functions
G. Bevilacqua, V. Biancalana, Y. Dancheva +2
In this paper we derive a new class of sum rules for products of the Bessel functions of first kind. Using standard algebraic manipulations we extend some of the well known propert…
Stray Magnetic Field Compensation with a Scalar Atomic Magnetometer
Jacopo Belfi, Giuseppe Bevilacqua, Valerio Biancalana +3
We describe a system for the compensation of time-dependent stray magnetic fields using a dual channel scalar magnetometer based on non-linear Faraday rotation in synchronously opt…
All-optical magnetometry for NMR detection in a micro-Tesla field and unshielded environment
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 field. Nuclear…
Measurement of diffusion coefficients of francium and rubidium in yttrium based on laser spectroscopy
C. de Mauro, R. Calabrese, L. Corradi +9
We report the first measurement of the diffusion coefficients of francium and rubidium ions implanted in a yttrium foil. We developed a methodology, based on laser spectroscopy, wh…
Saturated absorption spectroscopy: elimination of crossover resonances by use of a nanocell
A. Sargsyan, D. Sarkisyan, A. Papoyan +6
It is demonstrated that velocity selective optical pumping/saturation resonances of reduced absorption in a Rb vapor nanocell with thickness \textit{L=} , 2, and 3 (resona…
All optical sensor for automated magnetometry based on Coherent Population Trapping
J. Belfi, G. Bevilacqua, V. Biancalana +2
An automated magnetometer suitable for long lasting measurement under stable and controllable experimental conditions has been implemented. The device is based on Coherent Populati…
