The bulk Josephson responce of the d-g-wave cuprate superconductor

Abstract

We consider the implications of the small Fermi surface for the ab-plane microwave absorption. The small Fermi surface results in two superconducting condensates. Linear combinations of these condensates correspond to the d- and g-wave pairings. Microwave electric field applied in the ab-plane induces Josephson transitions between the condensates. Dependence of the absorption upon direction, amplitude and frequency of the external microwave field is calculated. Results of the calculation are compared with the observed recently novel non-linear phenomena in microwave absorption of $YBaC{u}_2{O}_{7-\delta }$ single crystals.
