“…In this case an appearance of the superfluid fraction of 3 He in aerogel influences resonant properties of the VW. Experiments with aerogel attached to the VW have been done previously only with silica aerogel [1,2,3,4] where superfluid phases (A-like and B-like) have the same order parameters as A and B phases of bulk 3 He. These experiments have allowed to estimate the temperature dependence of the superfluid fraction in A-like and Blike phases as well as to detect an influence of the superfluid flow on the texture of the order parameter in the A-like phase.…”

We present experiments on nematic aerogel oscillating in superfluid 3 He. This aerogel consists of nearly parallel mullite strands and is attached to a vibrating wire moving along the direction of the strands. Previous nuclear magnetic resonance experiments in 3 He confined in similar aerogel sample have shown that the superfluid transition of 3 He in aerogel occurs into the polar phase and the transition temperature (Tca) is only slightly suppressed with respect to the superfluid transition temperature of bulk 3 He. In present experiments we observed a change in resonant properties of the vibrating wire at T = Tca and found that below Tca an additional resonance mode is excited which is coupled to the main resonance.

“…In this Letter, we present results of high magnetic field experiments in superfluid 3 He in nematic aerogel, wherein the solid 3 He layers on the aerogel strands have been replaced by 4 He. We use a vibrating wire (VW) resonator with the aerogel attached to it, as in previous VW experiments with 3 He in silica aerogel [30,31]. We have measured temperature dependencies of resonance properties of the resonator -the full width at half-maximum (FWHM) and the resonance frequency (f a ) -and detected superfluid transitions, which we attribute to transitions between normal and β, β and distorted β phases.…”
