Zidong Wang, Malcolm J. Grimson

摘要:

利用一种具有界面线性磁电耦合的复合多铁性链,研究了其在外加磁场或电场作用下的磁响应和电响应。模拟使用连续自旋动力学通过磁自旋和电赝自旋的朗道-利夫希茨-吉尔伯特方程。结果表明,磁化强度和极化的分布的准确描述所施加的电场和磁场,分别诱导。

英文摘要:

A composite multiferroic chain with an interfacial linear magneto-electric coupling is used to study the magnetic and electric responses to an external magnetic or electric field. The simulation uses continuous spin dynamics through the Landau-Lifshitz-Gilbert equations of the magnetic spin and the electric pseudo-spin. The results demonstrate an accurate description of the distribution of the magnetisation and polarisation are induced by applied electric and magnetic field, respectively.
