Texture of superfluid He-3 probed by a Wigner solid

The resistivity of the Wigner solid floating on the free surface of superfluid He-3 has been measured in both the A and B phases down to 200 mu K in the magnetic field. The resistivity in the A phase shows the asymptotic behavior to the temperature-square dependence at low temperatures. The temperature dependence is successfully explained by the uniform (l) over cap texture oriented normal to the surface and by the specular scattering of quasiparticles excited along (l) over cap vector. In the B phase, the resistivity exhibits the exponential decrease at low temperatures. The steep increase of the resistivity observed at high magnetic field is attributable to the nonuniform texture of the field-distorted order parameter induced near the surface.
