Figure 10From: Soft magnetic properties of nanocrystalline Fe73B7Si16Nb3Cu1 alloy after rapid heating under tensile stress Dependencies of core loss (a) and initial magnetic permeability (b) on frequency. Core annealed in furnace (T a = 550°C, t a = 90 min). Cores made of ribbon heated by electric current (j h = 42 A/mm2, t h = 3.7 s) under the tensile stress in the range 0 ≤ σ ≤ 90 MPa.Back to article page
