Abstract

We calculate the specific heat of superfluid 3 He film thinner than the coherence length. In such a thin film, quantization on the confined direction makes eigenstates discrete, thus there appears a set of Fermi disks which are just like subband. Because of both the discreteness and ABM-like energy gap, the specific heat exhibits Schottky type character, which becomes conspicuous in special thin region.
