Abstract
Model of the hysteresis loop of soft-magnetic amorphous alloys with the usage of a modified linear fractional function
Highlights
The phenomenon of hysteresis is well-known in Physics, technology, Economics and other branches of science
The magnetic hysteresis loop (HL) is one of the main characteristics of ferro- and ferrimagnets that are used in various electrical products, such as rotors and stators of electric motors and generators, transformers, magnetic shields, magnetic modulators, magnetic sensors for various purposes [1]
Comparison of calculations and experiments was carried out for representatives of three groups of amorphous soft magnetic alloys: an iron-based alloy of the nominal composition Fe77Ni1Si9B13, an alloy based on cobalt with the composition Co68Cr4Fe4Si13B11, as well as an alloy based on Fe-Co with the composition Fe56Co25B14Si5
Summary
The phenomenon of hysteresis is well-known in Physics, technology, Economics and other branches of science. In Physics, hysteresis dependences are found for various materials with a nonlinear response to external action, in particular, for ferromagnets. The resulting models can be used by designers to calculate the designed devices, physicists — to study the features of magnetization reversal processes, materials scientists — to predict the magnetic properties under various effects on the material. Requirements for the accuracy of description, universality (possibility of using for a wide range of magnetization reversal fields), and a small number of parameters used can be imposed on the HL model. The optimal model for forecasting can be considered a model, the parameters of which have a clear physical meaning, and the behavior of which can be predicted
