Paper Abstract

A 4-channel YBa2Cu3O7-y (YBCO) thin film dc-SQUID magnetometer was fabricated. Biomagnetic measurements were performed by using the 4 channel SQUID array at 77$KAPPA in a magnetically shielded room. We have successfully measured 4 channel magnetocardiac signals clearly in real time mode. The best magnetic field resolution of the four SQUIDs was 370fT/Hz1/2 at 10Hz and 200fT/Hz1/2 in the white noise region.
