  • In superconducting thin films of a few atomic layers, surface and bulk orders may compete. Here, the authors measure how the Pearl length, which characterizes the distribution of magnetic field in vortices, varies with thickness in NbSe2, showing that surface superconductivity dominates at low thickness.

  • A nonreciprocal critical current is known as the superconducting diode effect (SDE). Here, the authors use SQUID-on-tip to study SDE in a EuS/Nb bilayer and find that the stray field from magnetized EuS creates screening currents in the Nb, which lead to SDE by affecting vortex flow dynamics.
