    We have designed and fabricated a very low noise integrated dc Superconducting QUantum Interference Device (SQUID) magnetometer on a 4×4 mm2 chip. The white flux noise at 1 kHz is 6×10−7Φ0/√Hz . This corresponds to a flux density noise of 3.4fT/√Hz  and a coupled energy resolution of 32 h. The 1/f noise corner frequency is 10 Hz and the 1/f flux noise at 1 Hz is 2×10−6Φ0/√Hz .
