Abstract

The sol-gel auto combustion route was used to synthesis Mn-Cu-Cd-Gd ferrite\graphene nanoplatelets composites having chemical formula Mn0.5Cu0.25Cd0.25Fe1.97Gd0.03O4/Graphene nanoplatelets (MCCFG/GNPs composites) (where GNPs wt% = 0.0wt%, 1.25wt%, 2.5wt%, 3.75wt%, 5wt%). The incorporation of GNPs in the MCCFG sample enhanced the crystallite size from 35.89 nm to 58.92 nm. Raman modes of vibration also confirmed the spinel structure. The resistivity was reduced and optical bandgap energy was increased with increasing content of GNPs. Moreover, both dielectric constant and saturation magnetization was reduced with the insertion of GNPs in the MCCGF spinel lattice.

Mn-Cu-Cd-Gd铁氧体\石墨烯纳米片复合材料的光谱、电学和介电性能的估计

采用溶胶-凝胶自燃烧的方法合成了Mn-Cu-Cd-Gd铁氧体\石墨烯纳米片复合材料，其化学式为mn0.5 cu0.25 cd0.25 fe1.97 gd0.030 o4 /石墨烯纳米片(MCCFG/GNPs复合材料)(其中GNPs wt% = 0.0wt%， 1.25wt%， 2.5wt%， 3.75wt%， 5wt%)。GNPs的加入使mcfg的晶粒尺寸从35.89 nm增加到58.92 nm。拉曼振动模式也证实了尖晶石的结构。随着GNPs含量的增加，电阻率降低，光学带隙能量增加。此外，GNPs在MCCGF尖晶石晶格中的插入降低了介质常数和饱和磁化强度。
