Abstract
A simple method for simulating the hysteresis loops of the amorphous ribbons is described. A specific form of the Tchebyshev approximation has been proposed, offering a physical understanding of the irreversible magnetization process. We have divided the loop into two curves auxiliary semi-sum, h s, and semi-difference, hd, and with what the hysteresis loop approaches by means of the expression h = hs±h d. With the purpose of checking the proposed model, we have obtained the dynamic hysteresis loop of the Mo-Permalloy 4-79, and we have found that the simulation is in good agreement with the experimental data. The hysteretic energy losses obtained are 13.16 J/m3 while the experimental value is 13.14 J/m3. © 2003 Published by Elsevier B.V.
