Unusual critical currents in quasi-one-dimensional superconducting aluminum two-width structures in a magnetic field
V. I. Kuznetsov, O. V. Trofimov
We measured unusual critical currents as functions of temperature in the zero field and as functions of a magnetic field perpendicular to the substrate surface at a given temperatu…
Shift of the maxima of the critical currents of different polarity relative to the zero magnetic flux along the flux axis in a superconducting asymmetric aluminum ring
V. I. Kuznetsov, O. V. Trofimov
We measured the rectification of an ac voltage in a structure of superconducting circularly-asymmetric aluminum rings in series, permeated with a magnetic flux and biased with a lo…
Critical temperatures and critical currents of wide and narrow quasi-one-dimensional superconducting aluminum structures in zero magnetic field
V. I. Kuznetsov, O. V. Trofimov
We measured the critical temperatures and critical switching and retrapping currents of wide and narrow thin-film quasi-one-dimensional superconducting aluminum structures of the s…
Negative nonlocal and local voltages (resistances) in a quasi-one-dimensional superconducting aluminum structure
V. I. Kuznetsov, O. V. Trofimov
To study a nonlocal electron transport in an aluminum superconducting quasi-one-dimensional structure, we measured negative nonlocal (local) direct current voltages in the structur…
