Abstract
YBa2Cu3O7-x based monolithic integrated dc SQUID magnetometers, consis ting of a dc SQUID integrated with a flux transformer on a single bicr ystalline substrate, have been fabricated and characterized. The devic es consist of four layers, including two superconducting layers, and f irst realizations operate up to 73 K. A maximum voltage modulation of 32 muV is observed at 40 K. A field sensitivity of 0.17 pT/square-root Hz is obtained above 200 Hz at 45 K and 0.49 pT/square-root Hz at 1 H z and 65 K.
