| Abstract(in English) | Designs and measurements for low noise YBCO dc-SQUIDs have been made. It was found that the parameters of YBCO devices could been controlled well and substrates with low dielectric constant were useful for high output voltage and low noise SQUIDs. We have designed a YBCO dc-SQUID with a cross section of junction as small as 0.1μm^2. The measured energy resolution (ε^w) was about 1.76×10^<-33>J/Hz～2.7h at 4.2K. This result demonstrates that the quantum noise limit can be achieved with the optimized YBCO dc-SQUIDs. |
