The increased capabilities of coupling more and more materials through functional interfaces are paving the way to a series of exciting experiments and extremely advanced devices. Here we focus on the capability of magnetically inhomogeneous superconductor/ferromagnet (S/F) interfaces to generate spin-polarized triplet pairs. We build on previous achievements on spin-filter ferromagnetic Josephson junctions (JJs) and find direct correspondence between neat experimental benchmarks in the…

Singlet and triplet Cooper pair splitting in superconducting-semiconducting hybrid nanowires
In most naturally occurring superconductors, electrons with opposite spins are paired up to form Cooper pairs. This includes both conventional s -wave superconductors such as aluminum as well as
Realization of 0 - $\pi$ states in SFIS Josephson junctions. The role of spin-orbit interaction and lattice impurities
Josephson devices with ferromagnetic barriers have been widely studied. Much less is known when the ferromagnetic layer is insulating. In this manuscript we investigate the transport properties of


Tuning of Magnetic Activity in Spin-Filter Josephson Junctions Towards Spin-Triplet Transport.
The first extensive characterization of spin polarized Josephson junctions down to 0.3 K, and the first evidence of an incomplete 0-π transition in highly spin polarized tunnel ferromagnetic junctions are presented.
Reversible control of spin-polarized supercurrents in ferromagnetic Josephson junctions.
It is shown that the use of a barrier comprising three F layers enables full control of the triplet supercurrent and, by using finite element micromagnetic simulations, can directly relate the experimental data to the theoretical models which provide a general framework to understand the role played by magnetic states in long-range supercurrent modulation.
Controlling the superconducting transition by spin-orbit coupling
Whereas there exists considerable evidence for the conversion of singlet Cooper pairs into triplet Cooper pairs in the presence of inhomogeneous magnetic fields, recent theoretical proposals have

The continuous development of superconducting electronics is encouraging several studies on hybrid Josephson junctions (JJs) based on superconductor/ferromagnet/superconductor (SFS) heterostructures,
Macroscopic quantum tunnelling in spin filter ferromagnetic Josephson junctions
Evidence for active quantum applications of S-F-S junctions is demonstrated, through the observation of macroscopic quantum tunnelling in Josephson junctions with GdN ferromagnetic insulator barriers, which paves the way to the active use of spin filter Josephson systems in quantum hybrid circuits.
Amplitude Control of the Spin-Triplet Supercurrent in S/F/S Josephson Junctions.
On-off control of the spin-triplet supercurrent is demonstrated in Josephson junctions containing three ferromagnetic layers by rotating the magnetization direction of one of the three layers by 90°.

This report follows recent developments in the controlled creation of long-range equal-spin triplet supercurrents in ferromagnets and its contribution to spintronics.
Long range triplet Josephson effect through a ferromagnetic trilayer
The coexistence of superconductivity and ferromagnetism is very rare in bulk systems. However, it can be easily achieved in artificially fabricated superconductor/ ferromagnet S/F heterostructures.
Spin-filter Josephson junctions.
It is shown that the strong suppression of Cooper pair tunnelling by the spin filtering of the I(F) barrier can be modified by magnetic inhomogeneity in the barrier and the field and temperature dependence of I(c) is strongly modified by the I (F).
