We study spin transport in a two-state mixture of ultracold Fermi gases near a Feshbach resonance. The strong interactions lead to extremely slow relaxation of spin currents. The relevant transport coefficients, the spin conductivity and the spin diffusion coefficient, are observed to attain universal minimal values, with the spin diffusion being given by hbar/m, where m is the atomic mass.

The ratio of spin conductivity and spin diffusion coefficient yields the spin susceptibility in these gases, showing the Curie law at high temperatures and a departure from the compressibility at low temperatures, that we interpret as a signature for entering the Fermi liquid regime.
