Abstract
Magnetic after-effect measurements (MAE) on carbon or nitrogen doped α-iron show characteristic relaxation maxima. The microscopic nature of the MAE is briefly discussed and the measuring technique applying an LC oscillator is explained. Measurements on high-purity iron after different refinements are used to show the analysing sensitivity and limits. The results are compared to chemical analysis and internal friction measurements.
