摘要：

We present a multi-loop dc-SQUID magnetometer operated at 77 K. In a multi-layer process YBa2Cu3O7, PrBa2Cu3O7, and SrTiO3 films are deposited by KrF-excimer laser deposition on SrTiO3(100) substrates. The preparation consists of four film deposition and three patterning steps. We employ YBa2Cu3O7 Josephson junctions with artificial barriers of PrBa2 Cu3O7 in a ramp-type geometry. The characterization is made by electrical transport and by noise measurements. The measured magnetic field sensitivity of 1.25 nT/Phi(0) of our device fits well with the calculated value of 1.17 nT/Phi(0).
