| Abstract(in English) | We demonstrate that the low frequency noise in high Tc SQUID magnetometers can be reduced by forming slots in flux dams. We designed and fabricated directly coupled dc SQUID magnetometers with mesh structure using YBa_2Cu_3O_<7-x> thin film on SrTiO_3 substrate. In order to suppress the flux motion in the flux dams, we formed 5μm wide strip lines and slots along the GB of the flux dams. The FLL output was stable and the increase of low frequency noise was suppressed up to an applied field of 83 μT(field cool) and 40 μT(field change after zero field cool). However, another type of magnetometer with different geometry of flux dams showed a drift of FLL output. So, it is important to control the structure of the flux dams. |
