Superconductors containing mesoscopic artificially-engineered defects are orders of magnitude more resistant to the destructive effect of the magnetic field. We present scanning tunnelling microscopy study of the vortex lattice configurations in a me

We report on dynamics of non-local Abrikosov vortex flow in mesoscopic superconducting Nb channels. Magnetic field dependence of the non-local voltage induced by the flux flow shows that vortices form ordered vortex chains. Voltage asymmetry (rectifi

Using scanning tunneling microscopy, we mapped the distribution of the local density of states in a single crystal superconductor heterostructure with an array of submicron normal metal islands. We observe the coexistence of strongly interacting mult

Enhanced vortex pinning in nanoscale-engineered superconductors increases the superconducting critical currents by orders of magnitude. Spatial imaging of vortices in these systems at high magnetic fields would provide further insight into the pinnin
