Abstract
There is currently a debate on whether or not the transverse relaxation time is finite at low temperature in spin-polarized Fermi liquids. The experimental results so far have been contradictory. In this paper, the first in a series of two articles, we present NMR measurements carried out in 6.2% 3He-4He mixture at 11.3 T down to 3.5 mK. A careful analysis of our data yields an anisotropy temperature T a = 6.1±1 mK, which is smaller than the values reported previously. The difference between this value and the earlier results is ascribed to restricted diffusion effects which were neglected in the previous analyses. The details of the analysis are given in the companion paper.

In fact, the magnetic field produced by the walls is very well approximated by the expression (1), with G 2 = −3µ 0 M wall/(8 \(\sqrt 2 \) R 2), where µ 0 is the permittivity of vacuum and M wall is the walls magnetization. The fit of NMR lineshape yields values of µ 0 M wall between 1 and 3 G.
