A method based on a dual frequency resonator to estimate physical parameters of superconductors from surface impedance measurements in a magnetic field
Nicola Pompeo, Kostiantyn Torokhtii, Andrea Alimenti +1
High frequency applications of superconductors in a dc magnetic field rely on the estimate of the characteristic crossover frequency between low and high losses. Customarily,…
Surface impedance measurements in superconductors in dc magnetic fields: challenges and relevance to particle physics experiments
Andrea Alimenti, Nicola Pompeo, Kostiantyn Torokhtii +1
Particle physics and radio-frequency (RF) superconductivity have driven each other on since the 1970s. The unique properties of superconductors (SC) have been the enabling keys for…
Impact of the superconductors properties on the measurement sensitivity of resonant-based axion detectors
Andrea Alimenti, Kostiantyn Torokhtii, Daniele Di Gioacchino +3
Axions, hypothetical particles theorized to solve the strong CP-problem, are presently being considered as strong candidates as cold dark matter constituents. The signal power of r…
Frequency span optimization for asymmetric resonance curve fitting
Kostiantyn Torokhtii, Andrea Alimenti, Nicola Pompeo +1
The wide application of the modern resonant measurement techniques makes all the steps of the measuring process, including data acquisition more efficient and reliable. Here we inv…
Pinning, flux flow resistivity and anisotropy of Fe(Se,Te) thin films from microwave measurements through a bitonal dielectric resonator
Nicola Pompeo, Andrea Alimenti, Kostiantyn Torokhtii +3
We report on the anisotropy of the vortex motion surface impedance of a \fst thin film grown on a CaF substrate. The dependence on the magnetic field intensity up to 1.2 T and…
Microwave measurements of the high magnetic field vortex motion pinning parameters in NbSn
Andrea Alimenti, Nicola Pompeo, Kostiantyn Torokhtii +4
The high frequency vortex motion in NbSn was analyzed in this work up to 12 T. We used a dielectric loaded resonator tuned at 15 GHz to evaluate the surface impedance of a…
