摘要：

A four-channel YBa2CU3O7-y thin film de SQUID magnetometer was fabricated. Biomagnetic measurements were performed by using the four-channel system at 77 K in a magnetically shielded room. We have successfully measured four-channel magnetocardiac signals clearly in real-time mode. The best magnetic field resolution of the four SQUIDs was 370 fT/Hz(1/2) at 10 Hz and 200 fT/Hz(1/2) in the white noise region.
