Abstract
The orientation of the order parameter in the A-like and B-like phases of superfluid 3He immersed in uniaxially compressed aerogel is reported. With the use of NMR methods, it is found that the orbital momentum of the A-and B-like phases is oriented along the deformation. In the A-like phase, a relatively narrow NMR line with an anomalously large negative frequency shift is observed. The Leggett frequency in the A-like phase, which shows the same energy gap suppression as in the B-like phase, is measured.

During the fast cooling of the Universe, fluctuations in the baryonic matter density should have been smoothed out by plasma waves. However, the dark matter fluctuations remain and explain the current amplitude of the relic radiation, in the analogous way that inhomogenity of local deformation in aerogel creates defects and texture in superfluid 3He (comment by Yu.M.B.).
