Spin diffusion in liquid ${}^3$He confined in planar aerogel

Abstract

We report the results of theoretical and experimental investigation of spin diffusion in the normal phase of liquid ${}^3$He confined in planar aerogel: a material consisting of nanostrands which are almost parallel to a specific plane and randomly oriented in this plane. Using spin echo technique we measure the spin diffusion coefficients in the directions perpendicular and parallel to the plane. We see good agreement between the experiment and the theory.
