The article presents the results of experiments in superfluid 3He, performed using a vibrating wire resonator with nematic aerogel attached to it. The transitions of 3He into a new superfluid phases: the polar phase, the β phase, and distorted A and β phases were detected by this technique. Additionally, experiments of studying A1 phase in nematic aerogel were performed, where a suppression of the transition temperature was investigated, which we attribut to the influence of magnetic scattering.
