Effect of pulse duration on current-induced selective oxygen migration in high-Tc superconductors

Fridrich Egyenes, Daniel Stoffels, Stefan Marinkovic +6

High current densities can induce the directional diffusion of atoms in metallic films. In YBa${}_2$Cu${}_3$O${}_{7-\hat{I}´}$ (YBCO), this electromigration process selectively acts on oxygen…
