SQUID magnetometer based on Grooved Dayem nanobridges and a flux transformer
Paper in proceeding, 2019
We report noise measurements performed on a SQUID magnetometer implementing Grooved Dayem nanobridge of YBCO as weak-links. The SQUID shows magnetic flux noise as low as 10μΦ 0}/Hz0.5. The magnetometer is realized by coupling the SQUID to a flux transformer with a two-level coupling scheme using a flip-chip approach. This improves the effective area of the SQUID and result in a magnetic field noise of 50fT/Hz0.5atT=77K.
