Abstract:
The paper studies the effect the temperature has on the magnetic properties of the Co79-xFe3Cr3Si15Bx amorphous alloy with different boron content. Magnetic saturation induction B-s and Curie temperature T-C decrease as the boron content increases. Within the range of relatively high temperatures, magnetic saturation induction B-s = mu M-0(s) is related to the temperature by B-s(T) similar to (T-C - T)(0.38). In the Co79-xFe3Cr3Si15Bx amorphous alloys with the Curie temperature of lower than 180 degrees C the initial permeability of 200,000 and the coercive force of 0.1 A/m were obtained. The high initial permeability of the amorphous alloy is attributed to the absence of the crystalline, magnetoelastic and induced magnetic anisotropy in this alloy. Low Curie temperature near which the permeability appreciably increases (Hopkinson effect) is another approach to the ideal magnetic softness. (C) 2015 Elsevier B.V. All rights reserved.
