理解多铁性耦合是多铁性领域的关键问题之一。从理论上讲，铁磁共振（FMR）是一种获得复合多铁性材料磁电耦合系数的途径。这一点，我们的证据，通过详细的分析和数值计算的FMR在无应变链的钛酸钡在tetraxide相接触，铁，包括退极化场的影响。FMR中的吸收功率的光谱被发现是敏感的界面电极化的方向和所施加的静电场。本文提出了一种利用铁磁电阻测量磁电耦合系数的方法。(C)2013年美国物理学会。[http：//dx.doi.org/10.1063/1.4772746]
Understanding the multiferroic coupling is one of the key issues in the field of multiferroics. As shown here theoretically, the ferromagnetic resonance (FMR) renders possibly an access to the magnetoelectric coupling coefficient in composite multiferroics. This we evidence by a detailed analysis and numerical calculations of FMR in an unstrained chain of BaTiO3 in the tetragonal phase in contact with Fe, including the effect of depolarizing field. The spectra of the absorbed power in FMR are found to be sensitive to the orientation of the interface electric polarization and to an applied static electric field. Here, we propose a method for measuring the magnetoelectric coupling coefficient by means of FMR. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4772746]
