Abstract
A scanning HTS SQUID microscope for magnetic imaging samples at room temperature and atmospheric pressure has been developed. A sensor for the microscope was completed by a bicrystal dc SQUID and a needle made of soft magnetic material, which serves as a magnetic flux guide (MFG). This sensor has allowed magnetic imaging of the warm samples with spatial resolution of the order of 100 μm. Line scans of magnetic field produced by the current-carrying wires are measured and compared with results of a numerical modeling. The influence of the MFG on the image details has been studied.
