Abstract
We report results of low frequency nuclear magnetic
resonance (NMR) experiments
in the superfluid polar phase of 3He which is stabilized by a new type
of "nematic"
aerogel - nafen. We have found that an interaction between transverse and
longitudinal NMR modes may essentially influence the spin dynamics.
Theoretical formulas for
NMR resonant frequencies are derived and applied for
interpretation of the experimental results.
