In highly charged soft matter systems that are dominated by long-range electrostatic interactions, such as lamellar phases of surfactants, ion correlations need to be accounted for in order to qantitaively describe the forces.

We have demonstrated spin pumping from a paramagnetic state of an insulator La₂NiMnO₆ into a Pt film. Single-crystalline films of La₂NiMnO₆ which exhibit a ferromagnetic order at T_C≈270  K were grown by pulsed laser deposition. The inverse spin Hall voltage induced by spin-current injection has been…
