A lead-free multiferroic double perovskite BiHoNiTiO₆ (BHNT) was prepared at high temperature following mixed oxide solid state reaction mechanism. Structural evaluation by X-ray diffractogram suggested monoclinic crystal system for the BHNT. SEM images showed homogeneous morphology with almost similar and uniform grain distribution. The compound possessed low value of tanδ even at a high temperature (400^oC) at 100 kHz. Evaluation of the dielectric and electrical plots with frequency and temperature obtained from the impedance spectroscopy revealed that the contributions of grains, grain boundaries and electrode has profound effect on the above properties. These plots are very much helpful to understand the conduction mechanism and microstructure characteristics of the electronic material. The experimental real and imaginary impedance data were modelled by designing an equivalent circuit with the capacitance and resistance parameter. The transport characteristics like σ_ac (ac conductivity), electrical modulus and magneto-electric effect of the material were also reported in this paper.

根据混合氧化物固态反应机理，在高温下制备了无铅多铁性双钙钛矿BiHoNiTiO ₆ (BHNT)。X 射线衍射图的结构评估表明 BHNT 为单斜晶系。SEM 图像显示出具有几乎相似且均匀的晶粒分布的均质形态。即使在高温 (400 ^oC) 100 kHz。从阻抗谱获得的频率和温度的介电和电图的评估表明，晶粒、晶界和电极的贡献对上述特性具有深远的影响。这些图对于了解电子材料的导电机制和微观结构特性非常有帮助。通过设计具有电容和电阻参数的等效电路，对实验实部和虚部阻抗数据进行建模。本文还报道了材料的输运特性，如 σ _ac（交流电导率）、电模量和磁电效应。
