In this study, BT-CFO based multiferroic composite were synthesized using solid state method by adding different compositions (i.e. 5%, 10% & 15%) of Cobalt Ferrite (CFO) in Barium Titanate (BT). XRD pattern showed sharp peaks of BT and CFO exhibiting crystalline nature of composite. The morphological structure was determined using FESEM, which also confirmed a uniform grain size distribution. Dielectric study was done by varying the temperature at a certain frequency value. Further, magnetic and ferroelectric properties of BT-CFO composite were studied by vibrating sample magnetometer (VSM) and PE–hysteresis loop, resulting in enhancement of magnetization and polarization as the amount of CFO increases in BT. In addition to this, BT-CFO composites exhibited a significant magneto-electric effect. The maximum value of ME coefficient is calculated as 5.506 mV/Cm-Oe for 10% CFO in BT at frequency of 10KHz, and at Hac = 1Oe.

本研究采用固态合成法，在钛酸钡（Barium Titanate, BT）中掺入不同组分（即5%、10%与15%）的钴铁氧体（Cobalt Ferrite, CFO），制备得到基于BT-CFO的多铁性复合材料。X射线衍射（X-ray Diffraction, XRD）图谱显示BT与CFO的特征衍射峰尖锐清晰，表明该复合材料具备结晶态特性。采用场发射扫描电子显微镜（Field Emission Scanning Electron Microscopy, FESEM）表征了复合材料的形貌结构，同时证实其晶粒尺寸分布均匀。本研究通过固定测试频率、改变温度的方式开展了介电性能研究。进一步地，分别采用振动样品磁强计（Vibrating Sample Magnetometer, VSM）与极化-电场回滞环（PE–hysteresis loop）对BT-CFO复合材料的磁学与铁电性能进行了测试，结果表明随着BT基体中CFO掺量的提升，复合材料的磁化强度与极化强度均得到增强。此外，BT-CFO复合材料表现出显著的磁电效应。在测试频率为10千赫兹、交变磁场强度Hac=1奥斯特的条件下，当BT中CFO掺量为10%时，其磁电系数的最大值经计算可达5.506 mV/(cm·Oe)。
