Field-free superconducting diode and tunable vortex dynamics in NbN/FePt stripe-domain heterostructures
Juan C. Zapata, Emilio De Biasi, Martin Sirena +2
We demonstrate reconfigurable, field-free superconducting diode behavior in NbN/FePt and NbN/AlN/FePt heterostructures with remanent stripe domains in the FePt layer. NbN films 10…

High-Efficiency Field-Free Superconducting Diodes in MoN/FePt Bilayers
Juan S. Cruz, Emilio De Biasi, Juan C. Zapata +3
Near-ideal, field-free superconducting diode behavior is demonstrated in room-temperature-grown MoN/FePt bilayers. The response is consistent with remanent FePt stripe domains…
