Dependence of the phase and magnitude of the response of Y-Ba-Cu-O edge transition bolometers on the superconducting transition is studied. The responses of both large and small area devices were investigated and several anomalies are observed. The response of small area LaAlO 3 devices considerably differed from that expected based on the dR/dT curve. This discrepancy is observed to be strongly dependent on the superconducting transition. Both the phase and magnitude/(dR/dT) of the response of the devices showed abrupt changes for below the T c-onset when measured versus temperature, while the phase variation also showed strong dependence on the modulation frequency. We present the analysis and propose mechanisms responsible for the modulation frequency dependence of the response characteristics versus temperature, within the superconductivity transition region of the devices.

“…Third harmonic techniques are particularly developed in optics 1 , and in the physics of semiconductors 2,3 . It is also possible to explore superconductor properties with such techniques as was already done for thermal properties in bulk and thin film materials [4][5][6] , for magnetic response 7 , non-linear effects in YBa 2 Cu 3 O 7−δ bicrystal Josephson junctions 8 and the nonlinear response in the vortex state 9 .…”

The generation of harmonics of the voltage response is considered when an AC current is applied through a superconducting film above Tc. It is shown that almost at all temperatures the mechanism of the temperature oscillations created by the AC current and the temperature dependence of the resistance dominates over the isothermal nonlinear electric conductivity. Only in a narrow critical region close to Tc the latter is essential for the generation of the harmonics. A detailed investigation of harmonics generation provides an accurate method for measuring the thermal boundary conductance between the film and the insulating substrate. The critical behaviour of the third harmonic will give a new method for the determination of the lifetime of metastable Cooper pairs above Tc. The comparison of the calculated fifth harmonics of the voltage with the experiment is proposed as an important test for the applicability of the employed theoretical models.

“…Particularly, a third harmonic signal is a consequence of non-linear effects and its measurement is a powerful technique to investigate, and moreover, to discriminate between the different possible origins of these non-linearities. Different techniques of third harmonic measurement exist for investigating properties of HTSC devices especially in microwave range [2]- [6], or for characterizing material properties such as thermal conductivity [7]- [11], specific heat [11], current response [12], or critical temperature [13].…”

In this paper, we report on the sharp peak observed in the third harmonic voltage response generated by a bias sinusoidal current applied to several strips patterned in a YBa2Cu3O 7−δ thin film and in two La1−xSrxCuO4 thin films, when the temperature is close to the normal-superconductor transition. The lambda-shaped temperature dependence of the third harmonic signal on the current characteristics is studied. Several physical mechanisms of third harmonic generation are examined.
