✦ Synopsis

It is shown that phonons in this films, "cut off" from a simple lattice, possess a gap whose magnitude depends upon the thickness of the film. Due to the presence of the gap, the specific heat of the film for T~-0 changes approximately as T l exp(-const/T). This behaviour of the specific heat can be used for experimental verification of the existence of the phonon gap.

Iron thin films have been grown by DC magnetron sputtering using Si(100) wafers as substrates, and then oxidized in a well-controlled oxygen atmosphere in the vacuum chamber. Film thickness is about 50 nm, and grains forming these samples do not exceed 20 nm. In order to control structural propertie
