  journal={Physical Review B},
We report on nonlocal spin transport in mesoscopic superconducting aluminum wires in contact with the ferromagnetic insulator europium sulfide. We find spin injection and long-range spin transport in the regime of the exchange splitting induced by europium sulfide. Our results demonstrate that spin transport in superconductors can be manipulated by ferromagnetic insulators, and opens a path to control spin currents in superconductors.

In this review, the experimental situation on nonequilibrium spin injection into superconductors is discussed, and open questions and possible future directions of the field are outlined.
Very large flux-flow spin Hall effect in type-II superconductors
We predict the very large spin Hall effect in type-II superconductors which mechanism is drastically different from the previously known systems. We find that in the flux-flow regime the spin is
Coupled Spin and Heat Transport in Superconductor Hybrid Structures
Superconductor–ferromagnet nanoscale hybrid structures have attracted considerable theoretical and experimental efforts, both due to the fundamental question of the competition of superconductivity
Magnetization in Superconductor–Ferromagnetic Metal Bilayers Induced by the Inverse Proximity Effect
Within the Green’s function formalism, the magnetization induced by the inverse proximity effect in bilayers containing a superconductor and a strongly spin-polarized ferromagnetic metal is studied.
Nonlocal thermoelectric effects in high-field superconductor-ferromagnet hybrid structures
We report on the experimental observation of nonlocal spin-dependent thermoelectric effects in superconductor-ferromagnet multiterminal structures. Our samples consist of a thin superconducting
Recovering of superconductivity in S/F bilayers under spin-dependent nonequilibrium quasiparticle distribution
We study theoretically the influence of spin accumulation on superconductivity in a superconductor/ferromagnet bilayer. It is well known that the superconductivity in Superconductor/Ferromagnet (S/F)

We investigate electronic thermal rectification in ferromagnetic insulator-based superconducting tunnel junctions. Ferromagnetic insulators coupled to superconductors are known to induce sizable spin


Thin-film superconductor in an exchange field.
A large effective internal field in the Al film is found, which gives rise to extra Zeeman splitting in the superconducting quasiparticle density of states and which is attributed to the exchange interaction between the Eu ions and the Al conduction electrons.
Charge and spin transport in mesoscopic superconductors
The observed long-range chargeless spin transport opens a new path to manipulate and utilize the quasiparticle spin in superconductor nanostructures.
Extremely long quasiparticle spin lifetimes in superconducting aluminium using MgO tunnel spin injectors.
It is reported that spin-polarized quasiparticles in superconducting aluminium layers have surprisingly long spin lifetimes, nearly a million times longer than in their normal state.
Long-range spin-polarized quasiparticle transport in mesoscopic Al superconductors with a Zeeman splitting.
It is proposed that the relaxation length of the spin signal shows a nearly linear increase with magnetic field, hinting at a freeze-out of relaxation by the Zeeman splitting, rather than a renormalized spin-diffusion length.
Absolute spin-valve effect with superconducting proximity structures.
The feasibility of the absolute spin-valve effect for a certain interval of voltages in a system consisting of two coupled trilayer structures in hybrid superconductor-normal-metal-ferromagnet structures is demonstrated.
Quasiclassical theory of superconductivity near magnetically active interfaces.

Spin injection from a normal metal into a mesoscopic superconductor
We report on nonlocal transport in superconductor hybrid structures, with ferromagnetic as well as normal-metal tunnel junctions attached to the superconductor. In the presence of a strong Zeeman

Spin imbalance and spin-charge separation in a mesoscopic superconductor
Injection of spin-polarized electrons into a superconductor leads to both spin and charge imbalance. If charge relaxation occurs faster than spin relaxation, it is possible to observe excess spin at
Electron-spin polarization in tunnel junctions in zero applied field with ferromagnetic EuS barriers.
An electron-spin polarization P of as much as 80% has been observed in the tunnel current in Au/EuS/Al tunnel junctions and the value of P calculated from the tunneling theory using known barrier heights in EuS is consistent with the measured values.
