The Decay of Persistent Currents in Unsaturated Superfluid 4He Films
Persistent currents of unsaturated 4He films are observed to decay at a rate which depends strongly on film thickness. Preliminary results on the temperature dependence of the decay rate are reported. Possible models which might explain the observed features of the decays are discussed.

Phys. 26, 147 (1977)) fact that the presence of third sound does not destroy the stability of stable persistent currents is perhaps understandable. That such should also be the case for persistent currents which decay is perhaps somewhat of a surprise.ADSCrossRefGoogle Scholar
