摘要：
The internal oscillation-mixing in TiBaCaCuO thin-film microbridge junctions has been studied at liquid nitrogen temperature. The TIBaCaCuO thin-film microbridge junctions were fabricated by the wet-etching technique. As TIBaCaCuO superconducting material is very sensitive to magnetic fields, it is crucial to use a magnetic shielding system in the experiments. In the presence of a magnetic shielding system, we obtained a -37 dB mW sensitivity for a TIBaCaCuO Josephson internal oscillator-mixer which is close to that of a YBaCuO Josephson internal oscillator-mixer [1-3].
