Suppression of diamagnetism in superconducting nanorings by quantum fluctuations
Terhi T. Hongisto, K. Yu. Arutyunov
Zero resistance, diamagnetism (Meissner effect) and the energy gap in the excitation spectrum are the fundamental attributes of superconductivity. In nanoparticles with characteris…
Quantum fluctuations in ultranarrow superconducting nanowires
M. Zgirski, K. -P. Riikonen, V. Touboltsev +1
Progressive reduction of the effective diameter of a nanowire is applied to trace evolution of the shape of superconducting transition in quasi-one-dimensional aluminum stru…
Negative magnetoresistance of ultra-narrow superconducting nanowires in the resistive state
K. Yu. Arutyunov
We present a phenomenological model qualitatively explaining negative magnetoresistance in quasi-one-dimensional superconducting channels in the resistive state. The model is based…
Resistive state of quasi-one-dimensional superconductors: fluctuations vs. sample inhomogeneity
M. Zgirski, K. Yu. Arutyunov
The shape of experimentally observed R(T) transition of thin superconducting wires is analyzed. Broadening of the transition in quasi-1-dimensional superconducting channels is typi…
Tunneling spectroscopy of persistent currents in superconducting microrings
K. Yu. Arutyunov, T. T. Hongisto, D. Y. Vodolazov
It is shown that in a structure consisting of a superconducting ring-shaped electrode overlapped by a normal metal contact through a thin oxide barrier, measurements of the tunnel…
Critical temperature modification of low dimensional superconductors by spin doping
Pasi Jalkanen, Vladimir Tuboltsev, Ari Virtanen +2
Ion implantation of Fe and Mn into Al thin films was used for effective modification of Al superconductive properties. Critical temperature of the transition to superconducting sta…
