The article presents the results of experiments in superfluid 3He, performed using a vibrating wire resonator with a nematic aerogel glued to it, which allowed detecting transitions of 3He to new superfluid phases: to the polar phase, β-phase, and the distorted A- and β-phases. Experiments on observing the A1-phase in a nematic aerogel are also described, where the suppression of the transition temperature was studied, which we associate with the influence of magnetic scattering.
