| dc.description | Isotope effects in a multiband superconductor with a leading interband pairing channel are investigated. A relatively small electron-phonon contribution into the pair-transfer interaction can cause effects of observed magnitude. A multiband model which interpolates the cuprate properties is used for illustrative calculations. Isotope exponents of the transition temperature ($α$), supercarrier density ($α_n$), paired carrier effective mass ($α_m$) and of the penetration depth ($α_λ$) on the doping scale have been obtained. The known opposite trend of $α$ and $T_c$ is reflected. The trends of $α$ and $α_n$ are similar. In contrast with the usual assumption in the interband case $α_λ$ is driven by $α_n$, which overwhelmes $α_m$. | |
