The phase state of a spin-triplet Josephson junction containing three ferromagnetic layers is magnetically controlled. It is now well established that a Josephson junction made from conventional spin-singlet superconductors containing ferromagnetic layers can carry spin-triplet supercurrent under certain conditions. The first experimental signature of that fact is the propagation of such supercurrent over long distances through strong ferromagnetic materials. Surprisingly, one of the most…

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.

We show that superconducting correlations in the presence of non-zero condensate velocity can mediate the peculiar interaction between localized spins that breaks the global inversion symmetry of
Direct and inverse superspin Hall effect in two-dimensional systems: Electrical detection of spin supercurrents
A useful experimental signature of the ordinary spin Hall effect is the spin accumulation it produces at the sample edges. The superspin Hall current [Phys. Rev. B 96, 094512 (2017)] is a transverse

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°.

TLDR
Experimental observations provide strong evidence for induced spin-triplet pair correlations, which have been predicted to occur in superconducting-ferromagnetic hybrid systems in the presence of certain types of magnetic inhomogeneity.
A spin triplet supercurrent through the half-metallic ferromagnet CrO2
TLDR
A Josephson supercurrent is reported through the strong ferromagnet CrO2, from which it is inferred that it is a spin triplet supercurrent, and the underlying physical explanation is a conversion from spin singlet pairs to spin triplets at the interface.

Zero phase difference supercurrent in ferromagnetic Josephson junctions.
TLDR
It is claimed that the presence of even one magnetization vector in the system breaks the time reversal invariance of the Hamiltonian, which can lead to a zero phase difference supercurrent, unless the symmetry is restored by a combination of time reversal and a rotational symmetry.
