Advantages of Dual Hyperbolic Tangent Function Over Single Hyperbolic Tangent Function in Description of Hysteresis LoopsAdvantages of Dual Hyperbolic Tangent Function Over Single Hyperbolic Tangent Function in Description of Hysteresis Loops
International Review of Electrical Engineering-iree, 2016Co-Authors: Tomislav Barić, Vedran Boras, Hrvoje GlavašAbstract:If the mathematical description of the Magnetic Hysteresis loop branches should be simple, easy to use and should credibly describe the waveform Magnetic Hysteresis loop with a minimum number of parameters, then it inevitably leads to the description of Magnetic Hysteresis loop branches with a hyperbolic tangent function. This paper presents the advantages in description of Magnetic Hysteresis loop branches with a hyperbolic tangent function over other functions. The advantages in description of Magnetic Hysteresis loop branches with dual hyperbolic tangent function versus description with a single hyperbolic tangent function when the Magnetic Hysteresis loop has a very pronounced saturation region are provided. Also, this paper presents numerical difficulties in describing of Magnetic Hysteresis loop branches with a hyperbolic tangent function. Using soft Magnetic material, as an example, a numerical procedure for determining parameters in description of Magnetic Hysteresis loop branches with a single and two hyperbolic tangent functions is shown. The numerical results are analyzed and discussed.

a combined preisach hyperbolic tangent model for Magnetic Hysteresis of terfenol d
Journal of Magnetism and Magnetic Materials, 2015Co-Authors: Soheil Talebian, Mojtaba Ghodsi, Mohammad Reza Karafi, Yousef Hojjat, Shahed MirzamohammadiAbstract:Abstract This study presents a new model using the combination of Preisach and Hyperbolic Tangent models, to predict the Magnetic Hysteresis of Terfenol-D at different frequencies. Initially, a proper experimental setup was fabricated and used to obtain different Magnetic Hysteresis curves of Terfenol-D; such as major, minor and reversal loops. Then, it was shown that the Hyperbolic Tangent model is precisely capable of modeling the Magnetic Hysteresis of the Terfenol-D for both rate-independent and rate-dependent cases. Empirical equations were proposed with respect to Magnetic field frequency which can calculate the non-dimensional coefficients needed by the model. These empirical equations were validated at new frequencies of 100 Hz and 300 Hz. Finally, the new model was developed through the combination of Preisach and Hyperbolic Tangent models. In the combined model, analytical relations of the Hyperbolic Tangent model for the first order reversal loops determined the weighting function of the Preisach model. This model reduces the required experiments and errors due to numerical differentiations generally needed for characterization of the Preisach function. In addition, it can predict the rate-dependent Hysteresis as well as rate-independent Hysteresis.

phase field simulation of Magnetic Hysteresis and mechanically induced remanent magnetization rotation in ni mn ga ferroMagnetic shape memory alloy
Scripta Materialia, 2017Co-Authors: Qi Peng, Junjie Huang, Mingxiang Chen, Qingping SunAbstract:Abstract The Magnetic Hysteresis/coercivity in Ni-Mn-Ga is quantified in the phase-field model by introducing a Magnetic Resistant Field (MRF) into the Magnetic kinetic equation. Then microstructural processes of Mechanically-Induced Demagnetization (MID) and Magnetically/Mechanically-Induced Remanent Magnetization Rotation (MaIR/MeIR) are simulated. It is found that MID is a special case of MeIR, in which the remanent magnetization decreases significantly after its rotation. The remanent magnetization magnitude after MeIR will always be the smaller one of the initial remanent magnetization and the retentivity of ending martensitic variant. An analytical criterion determining remanent magnetization after MeIR under arbitrary demagnetization factors is proposed for potential applications.
