摘要: Ni-Zn ferrite and Bi2O3 composites were developed by the sol-gel method. The structural, magnetic, and dielectric properties were studied for all the prepared samples. X-ray diffraction (XRD) was performed to study the crystal structure. The results of field emission scanning electron microscopy (FE-SEM) showed that the addition of Bi2O3 can increase the grain size of the Ni-Zn ferrite. Magnetic properties were analyzed by a hysteresis loop test and it was found that the saturation magnetization and coercivity decreased with the increase of Bi2O3 ratio. In addition, the dielectric properties of the Ni-Zn ferrite were also improved with the addition of Bi2O3.
