Non-volatile multi-state electrothermal resistive switching in a strongly correlated insulator thin-film device

Farnaz Tahouni-Bonab, Matthias Hepting, Theodor Luibrand +7

Strongly correlated insulators, such as Mott or charge-transfer insulators, exhibit a strong temperature dependence in their resistivity. Consequently, self-heating effects can lea…

YBa $_{2}$ Cu $_{3}$ O $_{7}$ Josephson diode operating as a high-efficiency ratchet

Christoph Schmid, Alireza Jozani, Reinhold Kleiner +2

Using a focused He $^{+}$ beam for nanopatterning and writing of Josephson barriers we fabricated specially shaped Josephson junctions of in-line geometry in YBa $_{2}$ Cu $_{3}$ O $_{7}$ thin f…

Vortex matching at 6 T in YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ thin films by imprinting a 20 nm-periodic pinning array with a focused helium ion beam

Max Karrer, Bernd Aichner, Katja Wurster +9

Controlled engineering of vortex pinning sites in copper-oxide superconductors is a critical issue in manufacturing devices based on magnetic flux quanta. To address this, we emplo…
