Flux creep phenomenon in multifilamentary superconducting wires
The decrease of persistent induced currents was investigated in superconducting loops made of NbTi multifilamentary wires. A very low contact resistance was achieved, less than 10 −17 Ω, allowing for observation of the logarithmic time dependence of the flux creep. The results are discussed using a...

Zusammenfassung: | The decrease of persistent induced currents was investigated in superconducting loops made of NbTi multifilamentary wires. A very low contact resistance was achieved, less than 10
−17 Ω, allowing for observation of the logarithmic time dependence of the flux creep. The results are discussed using a new argument adapted from a phenomenological model of energy relaxations in spin glasses. |
