T. Kawae et al., THE INFLUENCE OF THE BOUNDARY-CONDITION FOR THE A-B TRANSITION OF SUPERFLUID HE-3 IN A CONFINED GEOMETRY, Physica. B, Condensed matter, 194, 1994, pp. 811-812
We have measured the A-B transition of superfluid He-3 confined in 1mu
m films by CW NMR method. When the boundary walls were covered with 4.
5 layers of He-4 film, the increase of the frequency shift of the A ph
ase and the elevation of the A-B transition temperature were observed.
