Kalalb, F. Kochorbe, M. Palistrant] A study is made of the thermodynamic properties of a three-band superconductor with an electron (or hole) mechanism of superconductivity. Interband carrier interaction is considered as the main reason for the occurrence of superconducting pairs. Expressions are obtained for the order parameters Δ n (T) (n=1, 2, 3), the specific heatC S, and the thermodynamic critical fieldH c in the region of low temperatures and also the temperatureT c of the superconducting transition, the jump in the specific heat (C S−CN) at the pointT=T c; and 2Δ n (0)/T c . It is shown that a characteristic feature in the behavior ofT c, (C S−CN), and Δ n (0) as functions of the carrier concentrationn is the presence of a smeared step. It is also shown that (C S−CN)/C N≤1.43 and that this ratio depends strongly on the relationship between the densities of the electron states of the considered bands.
