Abstract
The authors report measurements of the noise in a two-hole RF SQUID (superconducting quantum interference device) fabricated from bulk YBCO by an erosion technique in the frequency range 30 mHz to 1 kHz. Above 100 Hz the noise is essentially white with an RMS (root mean square) value of 5*10/sup -4/ phi /sub 0// square root Hz and is dominated by noise from the electronics. Below 10-Hz the noise power rises as 1/f/sup 0/9/.>Keywords
