| 摘 要： | 本文研究了离子代换对Li-Mg-Ti-Zn系铁氧体磁性(例如饱和磁化强度,磁晶各向异性、退磁态微波磁导率、铁磁共振线宽、矫顽力和剩磁比等)的影响。实验结果表明:非磁性离子代换量的变化引起材料磁特性的规律性变化。根据非磁性离子代换量和磁晶各向异性的关系,对实验结果作了合理的解释。

| Abstract: | Studied the effect of ion substitution in a Li-Mg-Ti-Zn ferrite system on magnetic properties, such as saturation magnetization, magnetocrystalline anisotropy, the real part of microwave permeability in the completely demagnetized state, ferromagnetic resonance line width, coercive force and magnetic remanence ratio etc. The experimental results show that the quantitative changes of nonmagnetic ion substitution cause the regular changes of magnetic properties. According to the relation between nonmagnetic ion substitution quantity and magnetocrystalline anisotropy, a reasonable interpretation for the experimental was obtained. |
