Figure 7From: Soft magnetic properties of nanocrystalline Fe73B7Si16Nb3Cu1 alloy after rapid heating under tensile stress Remagnetization loops of the cores made of ribbon. Heated by electric current (j h = 42 A/mm2, t h =3.7 s) under tensile stress in the range 0 ≤ σ ≤ 180 MPa and annealed in a furnace at T a = 550°C, t a = 90 min.Back to article page
