The Measurement for the Effective Anisotropy Constant of the Nanocomposite Permanent Magnetic Material Nd₂Fe₁₄B/α-Fe

Abstract:

The effective anisotropy constant and the saturation magnetization in nano composite Nd₂Fe₁₄B/α-Fe have been calculated by the law of approach to saturation (LATS) method. The applicability of the method has been analyzed. The calculated result shows that the LATS method is suitable for the calculation of the effective anisotropy constant and the saturation magnetization in nano composite permanent magnetic materials.
