The M-H behavior has displayed a ferromagnetic hysteresis loop with a wasp-waisted shape, which constricted in the middle section, while wider at above and below section.Further, various amount (1, 3, 5%)of NdFeB were mixed with Ni-Zn ferrites. The M-H behavior has shown markedly different coercivity and wasp-waisted hystsresis.

为了进行本研究，在样品制备上系以燃烧合成法制备奈米级镍锌铁氧体软磁磁粉，并与市售微米级铷铁硼硬磁磁粉加以均匀混合，最后压制成软硬磁复合之块材，并经由震荡样品磁性量测仪对软磁、硬磁与复合磁材加以量测以描绘出其磁滞曲线。

In this dissertation, based on glass microspheres and submicron silicon dioxide, the silver-coated core-shell shielding particles were prepared by liquid phase chemical deposition and layer by layer packing technology. The influences of the preparation conditions on the structure of the synthesized core-shell particles were also systemically studied. The conclusions are enumerated as follow:(1) Monodispersed submicron silicon dioxide spheres in the size range of 250～550 nm are synthesized by Sol-Gel method using ammonia as catalyst.
