Direct observation of a superconducting vortex diode Communications

Posted by in category: computing

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.
