Designing a Spin-Seebeck Diode

Simone Borlenghi, Weiwei Wang, Hans Fangohr, Lars Bergqvist, Anna Delin

摘要:

利用微磁学模拟,我们研究了自旋阀双层中存在的热梯度的自旋动力学。梯度的方向和强度允许选择性地激发每层的自旋波模式。这允许同步两个层的磁化旋进,并校正通过系统的能量流和磁化。我们的研究为自旋热电子学和纳米声子器件的应用提供了很好的机会。

英文摘要:

Using micromagnetic simulations, we have investigated spin dynamics in a spin-valve bi-layer in the presence of a thermal gradient. The direction and the intensity of the gradient allow to excite the spin wave modes of each layer selectively. This permits to synchronize the magnetization precession of the two layers and to rectify the flows of energy and magnetization through the system. Our study yields promising opportunities for applications in spin caloritronics and nanophononics devices.
