Calculation of Recoil Curves in Isotropic and Anisotropic Stoner–Wohlfarth Materials

With regard to hard magnetic materials, the recoil curves of hysteresis are applicable for motor designers. It is discussed how to calculate recoil curves of isotropic and anisotropic Stoner-Wohlfarth hysteresis, with different distributions as Gaussian and cos
ⁿ
(alpha). The Gaussian distribution is the most commonly used for representing texture in hard magnetic materials as NdFeB or ferrites. The Gaussian and cos
ⁿ
(alpha) distributions are compared and analytical functions are given. The analytical functions can reduce the time of calculation and also increase the accuracy of the results.
