We have measured a long-range supercurrent in Josephson junctions containing Co (a strong ferromagnetic material) when we insert thin layers of either PdNi or CuNi weakly ferromagnetic alloys between the Co and the two superconducting Nb electrodes. The critical current in such junctions hardly decays for Co thicknesses in the range of 12-28 nm, whereas it decays very steeply in similar junctions without the alloy layers. The long-range supercurrent is controllable by the thickness of the alloy… 
Area-dependence of spin-triplet supercurrent in ferromagnetic Josephson junctions
In 2010, several experimental groups obtained compelling evidence for spin-triplet supercurrent in Josephson junctions containing strong ferromagnetic materials. Our own best results were obtained

TLDR
It is shown that Josephson junctions containing particular combinations of strong ferromagnetic materials can carry spin-triplet supercurrent over distances of at least several tens of nanometres, whereas spin-singlet supercurrent in similar samples decays over a length scale of about 1 nm.
Observation of the dominant spin-triplet supercurrent in Josephson spin valves with strong Ni ferromagnets
We study experimentally nanoscale Josephson junctions and Josephson spin-valves containing strong Ni ferromagnets. We observe that in contrast to junctions, spin valves with the same geometry exhibit
Long-range proximity effect in Nb-based heterostructures induced by a magnetically inhomogeneous permalloy layer
Odd-frequency triplet Cooper pairs are believed to be the carriers of long-range superconducting correlations in ferromagnets. Such triplet pairs are generated by an inhomogeneous magnetism at the
Triplet superconducting correlations in oxide heterostructures with a composite ferromagnetic interlayer
The superconducting current induced by the penetration of the long-range triplet component of superconducting correlations into a composite ferromagnetic interlayer has been detected in
Long-range triplet proximity effect in multiply connected ferromagnet-superconductor hybrids
Applying the linearized Usadel equations, we consider the nucleation of superconductivity in multiply connected mesoscopic superconductor/ferromagnet (S/F) hybrids such as a thin superconducting ring
Observation of spin-triplet supercurrent in Co-based Josephson junctions
In the past year several groups have reported experimental evidence for spin-triplet supercurrents in Josephson junctions containing strong ferromagnetic materials. In this paper we present several
Evidence for Spin-Triplet Electron Pairing in the Proximity-Induced Superconducting State of an Fe-Doped InAs Semiconductor.
TLDR
Evidence for spin-triplet electron pairing in proximity-induced superconductivity in a ferromagnetic semiconductor (In,Fe)As is provided, and these spin- triplet natures in proximity super conductivity also reveal ferrom Magnetic properties of (In.Fe) as well as half-metallic materials.
Long range spin supercurrents in ferromagnetic CrO2 using a multilayer contact structure
We report measurements of long ranged supercurrents through ferromagnetic and fully spin-polarized CrO2 deposited on TiO2 substrates. In earlier work, we found supercurrents in films grown on
Reversible control of spin-polarized supercurrents in ferromagnetic Josephson junctions.
TLDR
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.
