The effect of inhomogeneous perturbations created by a nematic aerogel in liquid 3He on the form of the order parameter arising at the transition to the superfluid state is studied. It is shown that the stability boundary of the distorted polar Anderson–Brinkman–Morel phase can arise just on the superfluid transition line at certain characteristics of the nematic aerogel. A symmetry-based argumentation for the choice of aerogels most suitable for stabilizing the polar phase is given.
