摘要
为了实现石榴石型铁氧体(YIG)的低温烧结以适应LTCC技术,采用传统固相法,制备了多元离子(Bi^3+-Li^+-V^5+)协同取代的YIG铁氧体材料,系统研究了多元离子取代对材料结构特性、微观形貌和电磁性能的影响。结果表明,在900℃下烧结的样品其主晶相为石榴石相。随着取代量的增加,材料的密度、饱和磁化强度(4πMs)先增大后减小,铁磁共振线宽(△H)和矫顽力(Hc)先减小后增大。最终,在x=0.03得到了样品的最佳性能。
In order to realize low temperature sintering of garnet ferrite(YIG)suitable for LTCC technology,multivariate(Bi3+-Li+-V5+)co-substituted YIG ferrite material was prepared by traditional solid phase method.The effects of multivariate substitution on the structure,morphology and electromagnetic properties of YIG ferrite were systematically studied.The results show that the main crystal phase of the Bi^3+-Li^+-V^5+ion substituted sample sintered at 900℃is garnet.With increasing the substituents,the density and saturation magnetization(4πMs)increase first and then decrease,and the ferromagnetic resonance line width(ΔH)and coercivity(Hc)decrease first and then increase.As a result,the best performance was obtained for sample with x=0.03.
