Slippage of nonsuperfluid helium films

説明
Abstract We measured the slippage of nonsuperfluid 4 He films adsorbed on two kinds of substrates, grafoil and hectorite, and found that a large part of these films undergo slipping at low temperatures. Furthermore, it was found that the 4 He areal density dependence of the slippage is rather different between these substrates. In hectorite, the slippage is inhibited as the fluid state appears at absolute zero. On the other hand, in grafoil, this state does not suppress the slippage, at least, as the 4 He areal density is low. This may be attributed to the difference in the structure of these films.
