| 摘 要： | 采用氧化物法制备了NiCuZn铁氧体材料,研究了Bi2O3掺杂对其旋磁性能的影响。结果表明,在1～4wt%的范围内,随着Bi2O3含量的提高,铁磁共振线宽△H和介电损耗角正切tgδε都呈现出先减小后上升的趋势;并且在掺杂量为3wt%、烧结温度为900℃时,△H15kA/m、tgδε=6.5×10-4、Ms300kA/m,可用于低温共烧旋磁铁氧体基板的制备。

| Abstract: | The NiCuZn ferrite material was prepared by oxide method. The effect of Bi_2O_3 content on the gyromagnetic properties was investigated. It can be observed that with increasing Bi_2O_3 content in the range of 1-4wt%, both △H and tgδ_ε first decrease and then increase. Properties of △H
