“…These probes had small dimensions and high sensitivities (220 mV/mT) with resolutions of 10 µT over a broad frequency range. Besides GMR, other types of magnetoresistive sensors are also used for the imaging applications such as anisotropic magnetoresistance (AMR) [69] and tunnel magnetoresistance (TMR) [70], although the first being the most used in current works. Still, AMR effect sensors are actively used in imaging either for scanning MR microscopy [71] or in multichannel scanning systems [72].…”

“…As usually a MR sensor is sensitive to only one component of the field. However, the use of triple-axis magnetometers provides complementary information which can prove essential when a defect can be clearly evidenced in a specific field component [70].…”

“…Das dafür verwendete Messsystem muss insbesondere für schnelle Prüfungen zerstörungs-und abschabungsfrei arbeiten. In [1], [2] und [3] werden verschiedene magneto-resistive und -optische Sensoren vorgestellt, die potentiell verwendet werden könnten, aber für die Aufgabenstellung optimiert werden müssten. Ausgehend von [3] wird in diesem Beitrag ein Faraday-Magnetometer (engl.…”

“…The detection of missing or broken electrical interconnections in integrated circuits [5] is an NDT application in which Manuscript the spatial resolution is particularly critical. Consequently, the magneto resistive sensors used must be able to resolve deviations of the magnetic field due to changes of the current density distribution in the range of a few μm.…”
