Kurzbeschreibung (Abstract)
The electrophysical and dynamic parameters (Shapiro steps and detector response) of hybrid heterostructures based on oxide superconductors with the d-wave symmetry of the order parameter are studied. Deviation of the current-phase relation from the trivial (sinusoidal) form is revealed. It is shown in terms of a generalized Resistive Shunted Function model with the junction capacitance and higher harmonics of the current-phase relation has virtually no influence on the width of harmonic Shapiro steps but changes the scale of the step-width dependence on the ac current of an external electromagnetic field. In addition, it is shown that these dependences have no local minima if the current-phase relation (CPR) contains harmonics higher than the first. For heterostructures, the amplitudes and signs of the CPR harmonics are determined through comparison of theoretical and experimental data.
