Abstract
The internal friction Q-1/T/, of Cu samples covered by monolayers of stearic acid has been measured. The layers were grown by Langmuir-Blodgett technique. The obtained Q-1/T/ spectra exhibit the characteristic maximum at about 210 K which increases with the increasing number of deposited layers. Additionally Q-1 has been measured for Cu lubricated with liquid stearic acid. Such prepared layer causes the Q-1 maxima at about 340 K.
