Abstract

This paper reports on the dielectric properties of undoped and manganese doped aluminum iron oxide. The solid state reaction method was used to synthesis the samples. The dieletic function was measured over the frequency band 1kHz–10 MHz at room temperature. The real part of dielectric function shows the material in ferrimagnetic/ferromagnetic order. The negative value of imaginary part of dielectric function near Fabry–Perot resonance is found to be correlated with the magnetoelectric coupling. This magnetoelectric couping effect produces a transformation between magnetic energy and electric energy. The dispersion of imaginary part of electric modulus shows two relaxation time constant for undoped aluminum iron oxide and one relaxation time constant for manganese doped aluminum iron oxide. This effect of managanese doping and transformation of electric and magnetic energy near the Fabry–Perot resonance in aluminum iron oxide may be proclaimed as the novelty of this study.

锰掺杂铝氧化铁的介电行为及其在磁电传感和介电加热器件中应用的可能性
本文报道了未掺杂和掺杂锰的铝氧化铁的介电性能。采用固相反应法合成了样品。在室温下,在1khz - 10mhz频段测量介电函数。介电函数的实部表示材料按铁磁/铁磁顺序排列。在法布里-珀罗共振附近发现介电函数虚部的负值与磁电耦合有关。这种磁电耦合效应产生了磁能和电能之间的转换。电模虚部色散表现为未掺杂的铝氧化铁有两个松弛时间常数,掺杂锰的铝氧化铁有一个松弛时间常数。这种锰的掺杂和铝氧化铁中法布里-珀罗共振附近的电磁能转化的影响可以说是本研究的新颖之处。

期刊介绍: Reviews in Physics is a gold open access Journal, publishing review papers on topics in all areas of (applied) physics. The journal provides a platform for researchers who wish to summarize a field of physics research and share this work as widely as possible. The published papers provide an overview of the main developments on a particular topic, with an emphasis on recent developments, and sketch an outlook on future developments. The journal focuses on short review papers (max 15 pages) and these are freely available after publication. All submitted manuscripts are fully peer-reviewed and after acceptance a publication fee is charged to cover all editorial, production, and archiving costs.
