Control of magnetic permeability through electric field in magnetoelectric materials promises to create novel voltage tunable inductors (VTIs). VTIs synthesized using co-fired ceramic processing exhibit many advantages over traditional epoxy bonding method, but the internal residual stress in co-fired VTIs resulting from thermal expansion mismatch hinders a full exploitation of the tunability of permeability. To find the optimal condition for high tunability of co-fired VTIs, domain-level phase field modeling and computer simulation are employed to study co-fired magnetoelectric composites comprising NiZn ferrite and PZT. Two key factors important toward increasing the inductor tunability are systematically investigated: intrinsic magnetocrystalline anisotropy of the ferrite material and internal residual stress caused by the co-firing process. The simulations indicate that in order to achieve a large tunability, the tuned permeability should be confined within the linear region of the reciprocal of susceptibility and stress. Additionally, both magnetocrystalline anisotropy and residual stress should be as small as possible. These results provide a design strategy for realizing high-tunability co-fired VTIs.

共烧层压磁电复合材料中磁导率的电场控制：电压可调电感器应用的相场研究。
通过磁电材料中的电场控制磁导率有望创建新型的电压可调电感器（VTI）。使用共烧陶瓷工艺合成的VTI与传统的环氧粘合方法相比具有许多优势，但是由于热膨胀不匹配而导致的共烧VTI内部残余应力阻碍了渗透率可调性的充分利用。为了找到共烧VTI的高可调性的最佳条件，采用域级相场建模和计算机仿真研究了包括NiZn铁氧体和PZT的共烧磁电复合材料。系统地研究了对提高电感器可调谐性很重要的两个关键因素：铁氧体材料的固有磁晶各向异性和共烧过程引起的内部残余应力。仿真表明，为了获得较大的可调性，应将可调的渗透率限制在磁化率和应力倒数的线性范围内。另外，磁晶各向异性和残余应力都应尽可能小。这些结果为实现高可调共烧VTI提供了设计策略。
