Abstract Three different manganese oxide nanocomposites such as Mn3O4, Mn5O8, and Mn2O3 along with metallic-Mn were synthesized via a single route depending on calcination temperature. Structural, electrical, and magnetic properties were assessed for the synthesized nanocomposites. The real and imaginary parts of dielectric constants decreased at the lower frequency and then remained constant at the higher frequency for all the three types of nanocomposites. The permeability of the nanocomposites also followed the same order. Mn/Mn5O8 nanorods showed strong ferromagnetic behavior at room temperature although Mn-nanoparticles and Mn5O8 are paramagnetic and antiferromagnetic in nature respectively.

锰/锰氧化物纳米复合材料的室温铁磁行为

摘要 三种不同的氧化锰纳米复合材料，如Mn3O4、Mn5O8和Mn2O3以及金属-Mn，根据煅烧温度通过单一途径合成。对合成的纳米复合材料的结构、电学和磁学性质进行了评估。对于所有三种类型的纳米复合材料，介电常数的实部和虚部在较低频率下下降，然后在较高频率下保持不变。纳米复合材料的渗透性也遵循相同的顺序。Mn/Mn5O8 纳米棒在室温下表现出很强的铁磁性，尽管 Mn 纳米颗粒和 Mn5O8 分别具有顺磁性和反铁磁性。
