Аннотация
The data obtained from the investigations of characteristics of various bolometric elements based on HTS materials are analyzed. It is shown that the thermodynamic temperature fluctuations make a decisive contribution to the noise characteristics of perfect single-crystal films of YBa2Cu3O7–δ with axial orientation at right angles to the substrate used for thermal detection of electromagnetic radiation.
