Abstract: Noise performance of three types of high-transition-temperature direct current superconducting quantum interference device (DC SQUID) magnetometers fabricated from YBCO and STO films and operating at or near 77 K is investigated. Results indicate low frequency energy sensitivities in uncoupled SQUIDs and excess low-frequency noise in flip-chip coupled magnetometers.
