Abstract: The article presents the results of experiments in superfluid $^{3}$He, performed using a vibrating wire resonator with a nematic aerogel glued to it, which allowed detecting transitions of $^{3}$He to new superfluid phases: to the polar phase, $\beta $-phase, and the distorted A- and $\beta $-phases. Experiments on observing the $\rm A_1$-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.

Keywords: superfluidity of $\rm{^3He}$, nematic aerogel, vibrating wire.
