Superconducting Transition Temperature Modulation in NbN via EDL Gating
Erik Piatti, Alessandro Sola, Dario Daghero +7
We perform electric double-layer gating experiments on thin films of niobium nitride. Thanks to a cross-linked polymer electrolyte system of improved efficiency, we induce surface…
Control of bulk superconductivity in a BCS superconductor by surface charge doping via electrochemical gating
E. Piatti, D. Daghero, G. A. Ummarino +7
The electrochemical gating technique is a powerful tool to tune the \textit{surface} electronic conduction properties of various materials by means of pure charge doping, but its e…
Screening magnetic fields by a superconducting disk: a simple model
J. -G. Caputo, L. Gozzelino, F. Laviano +5
We introduce a simple approach to evaluate the magnetic field distribution around superconducting samples, based on the London equations; the elementary variable is the vector pote…
Critical state analysis in MgB2 bulk by means of quantitative MO technique
L. Gozzelino, F. Laviano, D. Botta +8
An extended magneto-optical (MO) analysis of samples cut from high-density pellets of MgB2 is reported. For sake of comparison some magnetic measurements and critical values are al…
