This presentation reports first results obtained with an optically pumped zero-field magnetometer (OPM) in combination with a micro fatigue setup. The small sample volume of about 1 mm³ allows metallographic characterization of specific material defects occurring during the fatigue process and linking them to features in the magnetic signal.enOptically Pumped Magnetometersfatigue testingMagneto-Mechanical Hysteresis620621poster
