Determination of the He3 superfluid-density tensor for the A and B phases

The classic technique of Andronikashvili has been used to determine the superfluid density of the A and B phases of superfluid He3. In the anisotropic A phase, the texture of the fluid is controlled through the interaction between the boundary condition on the l→ vector and an externally applied magnetic field. Comparison of measurements made for different textures clearly establish the anistropy of the superfluid density tensor for He3-A.
