The subject of the project is the study of interaction of nonlinear spin waves with spatially non-uniform potentials created due to the spatial variation of the static magnetic field. Within the second funding period we will focus on non-uniform potentials in spin-torque nano-oscillators. We will study the influence of the potential on the nonlinear dynamics of the nano-oscillators, as well as on the process of spin-wave emission and spin-wave coupling in arrays of oscillators. We will investigate ways enabling a controllable manipulation of the potentials providing the possibilities for efficient spin-wave emission and spin-wave exchange between neighboring spin-torque devices.

该项目的主题是研究非线性自旋波与由于静磁场的空间变化而产生的空间非均匀势的相互作用。在第二个资助期内，我们将专注于自旋扭矩纳米振荡器的非均匀电位。我们将研究势对纳米振荡器的非线性动力学的影响，以及对振荡器阵列中自旋波发射和自旋波耦合过程的影响。我们将研究的方法，使一个可控的操纵提供有效的自旋波发射和相邻的自旋扭矩设备之间的自旋波交换的可能性的潜力。
