| Abstract(in English) | We have fabricated Josephson Vortex Flow Transistors (JVFTs) with the Josephson junctions that were prepared using YBa_2Cu_3O_<7-δ> (YBCO) thin films grown on bi-crystal MgO(100) substrates. We measured the responses with the DC and AC current input to the control line that was inductively coupled to the array of the junctions. In AC measurements, we observed the high frequency responses of the JVFT to the input current of sine wave or square pulse wave. In the DC measurements, we observed the modulations of the critical current and the flow voltage. From the results, we estimated the parameters of the device, e. g. the mutual inductance and the self inductance, and calculated the upper of the operation frequency that the device potentially possessed these parameters. We also discuss the feasibility of higher frequency operation to embed it in single flux quantum (SFQ) logic circuit from the results of DC and AC responses. |
