| Research Abstract |
The miniaturized single-crystal devices composed of intrinsic Josephson junctions of lead-free and -substituted Bi_2Sr_2CaCu_2O_y high-T_c superconductors were fabricated for the above mentioned studies. The basic properties of them under magnetic field and microwave irradiation were studied experimentally and also by computer simulations. On the basis of the results, a couple of oscillator and detector composed of intrinsic Josephson junctions were constructed on a substrate, and the oscillation and detection of 0.7THz electromagnetic waves were successfully done by them using the Josephson vortex flow.
