| Abstract(in English) | We have investigated the influence of thermal cycling on TLF observed in NbN/MgO/NbN tunnel junctions epitaxially grown on MgO single crystals. The measured power density had a Lorentzian frequency dependence as expected from the Machlup formula for random telegraph noise. These spectra disappeared and appeared during repeated thermal cycling between 300 and 4.2K. We discussed in terms of the stresses develop in a thin film during thermal cycling because of the difference in the thermal-expansion coefficients for the film and the substrate. |
