Abstract
We have developed a monolithic low-temperature superconducting quantum interference device (SQUID) magnetometer and incorporated the device in a scanning microscope for imaging magnetic fields of room temperature samples. The instrument has a spatial resolution and a field sensitivity above a few hertz. We discuss design constraints on and potential applications of the SQUID microscope.
