Some comments on superfluid $^3$He placed in globally deformed
aerogel
G. A. Baramidze, G. A. Kharadze Tbilisi Ivane Javakhishvili State University
Abstract:
New experimental results focused on the behavior of the superfluid
$A$-like phase placed in globally deformed aerogel environment are
considered. We compare experimental data collected by using optically
attested axially stretched silica aerogel, on the one hand, and “nematically
ordered” aerogel consisting of nearly parallel
Al$_2$O$_3\cdot\text{H}_2$O polymer
strands, on the other. In the case of axially stretched silica aerogel the
point of view was adopted according to which the orbital anisotropy axis
$\hat{\text{l}}$ is long-ranged. The experiments were carried out by pulsed
NMR techniques in keeping the direction of an externally applied magnetic
field normal to aerogel stretching axis. We have generalized the
dipole-locked configuration for arbitrary angle of inclination of the
magnetic field with respect to aerogel stretching axis. The experimental
data collected in using “nematically ordered” aerogel can't be reconciled
with above-mentioned results.
