摘要： A non-destructive method of narrowing down the location of a failure in a sample includes a first step of acquiring first and second images of magnetic-field distributions obtained by scanning a laser beam irradiating first and second samples, respectively, and if there is a difference between the first and second images of the magnetic-field distributions, a second step of acquiring first and second current images from magnetic-field distributions acquired by scanning the first and second samples by a magnetic-field detector in a state in which a prescribed location on the first and second samples is being irradiated by the laser beam. The difference between the first and second current images is found and, based upon the difference image found, it becomes possible to identify a disparity in current paths relating to the prescribed location on the first and second samples.

摘要： A scanning SQUID microscope capable of high frequency magnetic field measurements uses a hysteretic SQUID detector and a pulsed sampling technique which permits to extend the bandwidth of the SQUID microscope to above GHz region. The system can be readily incorporated into a 4.2k scanning SQUID microscope for imaging chips at room temperature. By biasing the hysteretic SQUID with pulses of a predetermined amplitude, and adjusting a modulation flux applied to the hysteretic SQUID at a plurality of time delays between the activation of the sample under study and the bias pulse, the hysteretic SQUID can be switched on, and the modulation flux value corresponding to such a switching event as a function of time is considered as representation of the magnetic field emanating from the sample under study.
