Abstract

It is predicted that spin-singlet superfluidity can be realized in a submonolayer 3He film on the surface of thin film of superfluid 4He. The basic mechanism of the superfluidity is the attraction between 3He quasi particles arising from exchange of virtual third sound quanta. It is argued that the superfluid transition of 3He film is of Kosterlitz-Thouless nature if the 4He film is thick, and changes its nature as the 4He thickness is reduced, with a crossover thickness of ∼ 2 atomic layers. Several experiments are suggested to detect the new phase transition, to test whether the proposed mechanism is really working, and to examine the nature of the transition. The transition temperature is estimated to be in a temperature range attainable with a dilution refrigerator.
