Switching dynamics of oxygen-vacancy memristors based on cuprate superconductors Open
Resistive switching phenomena have attracted increased attention over the years because of their technological relevance, particularly for applications like nonvolatile memories and memristors, which are of much interest for emerging neuro…

Strain-Induced Enhancement of Spin Pumping in Pt/YIG Bilayers Open
Enhancing spin-to-charge (S$\rightarrow$C) conversion efficiency remains a key challenge in spintronic materials research. In this work we investigate the effect of substrate-induced strains onto the S$\rightarrow$C efficiency. On one hand…

Large-scale integration of MoS2 on high-TC superconducting YBa2Cu3O7 for the realization of Josephson devices Open
High-TC cuprate superconductors' growth conditions and their incompatibility with some of the most standard nanofabrication approaches make their large-scale integration with 2D materials (such as graphene, transition metal dichalcogenides…

Memristive effects in YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> devices with transistor-like structure Open
Cuprate superconductors are highly sensitive to disorder and oxygen stoichiometry; even minute variations of those parameters drastically change their electronic properties. In this work, we exploit this characteristic to engineer a memris…

Spin pumping in d-wave superconductor/ferromagnet hybrids Open
Spin-pumping across ferromagnet/superconductor (F/S) interfaces has attracted much attention lately. Yet the focus has been mainly on s-wave superconductors-based systems whereas (high-temperature) d-wave superconductors such as YBa2Cu3O7-…

Thermally assisted interlayer magnetic coupling through Ba0.05Sr0.95TiO3 barriers Open
We report on the interlayer exchange coupling across insulating barriers observed on Ni80Fe20/Ba0.05Sr0.95TiO3/La0.66Sr0.33MnO3 (Py/BST0.05/LSMO) trilayers. The coupling mechanism has been analyzed in terms of the barrier thickness, sample…
