Specifics of third-harmonic generation in Bi–Sr–Ca–Cu–O superconductors in the region of superconducting transition temperatures

Аннотация

The specifics of third-harmonic generation in Bi–Sr–Ca–Cu–O two-phase superconductors are studied. It is shown that the emergence of a maximum in the temperature dependence of the third-harmonic voltage in the region of superconducting transition temperatures is associated with the redistribution of the eddy current in the bulk of the semiconductor between its regions with different superconducting parameters (critical current and critical temperature).
