Electromechanical Magnetization Switching

Eugene M. Chudnovsky, Reem Jaafar

摘要:

我们证明了复合多铁性扭振子的磁矩可以通过电场进行开关。180 ° $^o$切换由自旋-旋转耦合引起,并且不像在固定磁体的情况下那样被磁矩和电场的不同对称性所禁止。分析方程描述的系统已经推导和研究数值。已经获得了显示开关所需的参数范围的相图。

英文摘要:

We show that the magnetic moment of a composite multiferroic torsional oscillator can be switched by the electric field. The 180$^o$ switching arises from the spin-rotation coupling and is not prohibited by the different symmetry of the magnetic moment and the electric field as in the case of a stationary magnet. Analytical equations describing the system have been derived and investigated numerically. Phase diagrams showing the range of parameters required for the switching have been obtained.
