Figure 11From: Soft magnetic properties of nanocrystalline Fe73B7Si16Nb3Cu1 alloy after rapid heating under tensile stress Remagnetization loops of cores. (Curve a) cut core with non-magnetic gap 0.045 mm (T a = 550°C, t a = 90 min) and (curve b) core made of ribbon heated by electric current (j h = 42 A/mm2, t h = 3.7 s) under tensile stress 100 MPa.Back to article page
