The anhysteretic magnetization curve is the key element of modeling magnetic hysteresis loops. Despite the fact that it is intensively exploited, known models of anhysteretic curve have not been verified experimentally. This paper presents the validation of four anhysteretic curve models considering four different materials, including isotropic, such as Mn-Zn soft ferrite, as well as anisotropic amorphous and nanocrystalline alloys. The presented results indicate that only the model that considers anisotropic energy is valid for a wide set of modern magnetic materials. The most suitable of the verified models is the anisotropic extension function-based model, which considers uniaxial anisotropy.

Speed And Accuracy

This article is concerned with the methods for experimentally determining the Anhysteretic Magnetization curve for soft magnetic materials. A new method based on the modern hysteresisgraph system is presented. Known modern and traditional methods based on fluxmeters are presented as well. The experimental results obtained with the described methods for isotropic Mn–Zn ferrite are compared. Lastly, results of validation on NANOPERM® nanocrystalline material are detailed and show negligible hysteresis. The new method allows for accurate Anhysteretic Magnetization curve measurement without software or hardware modifications of standard, commercially available hysteresisgraph systems. The speed and accuracy of the results are improved in comparison with other methods.

"The Co11Zr2 magnetic phase was obtained by a combination of melting, mechanical milling and high temperature annealing. The structure and magnetic properties of the obtained material were investigated. Even though the samples possessed low coercivity, it was shown that they possess uniaxial anisotropy. Keywords: hard magnetic materials, magnetic anisotropy, mechanical milling, high temperature annealing "

The calculations and experimental studies have shown that the intensity of nonlinear magnetization oscillations arising during the process of 180 pulsed magnetization reversal of real ferrite-garnet films with biaxial anisotropy weakly depends on the magnetization reversal pulse Hp frontf duration (in contrast to magnetic materials with uniaxial anisotropy). The pulsed magnetization reversalcurve, which provides a visual representation of the magnetization reversal speed saturation caused by the influence of nonlinear magnetization oscillations, analyzed for the first time.
