4He Adsorption and Superfluid Transition on C60 Academic Article uri icon

abstract

  • We present adsorption isotherm data of 4He on C60 for 1.50 K < T < 1.68 K determined by measurements of the frequency of quartz crystal microbalances (QCM's) coated with C60 films. We find a Kosterlitz-Thouless transition with a jump in the areal superfluid density close to predictions. By comparing the adsorbed 4He on two QCM's we derive an upper limit for the amount of 4He intercalated into C60 at low temperature of 0.05 4He atoms per C60 molecule. The low coverage portion of the adsorption data shows an apparent excess adsorption of 4He onto the C60. 1997 Plenum Publishing Corporation.
