The main goal of this project is to study nonlinear spin-wave propagation in laterally patterned magnetic nanostructures. Nonlinear spin-wave optical effects in micro-waveguides of different dimensionalities and properties of persistent nonlinear wave objects in parametrically pumped closed-loop nanowaveguides will be investigated. These studies will open a new research field, which we call “nonlinear spin-wave nanooptics”. The proposed investigations will contribute to the basic physics of universal nonlinear phenomena, such as solitons, modulational instabilities, pattern formation, and dynamic chaos. Besides, they are expected to open new possibilities for manipulation, amplification, and transmission of spin waves to be used in applications of magnetic nanostructures in microelectronic devices. The project brings together two world-leading research groups, possessing a unique experience in both magnetic dynamics and in patterned magnetic nanostructures.

该项目的主要目标是研究横向图案磁性纳米结构中的非线性自旋波传播。将研究不同维度的微波导中的非线性自旋波光学效应以及参数泵浦闭环纳米波导中持久非线性波物体的特性。这些研究将开辟一个新的研究领域，我们称之为“非线性自旋波纳米光学”。所提出的研究将有助于普遍非线性现象的基础物理学，例如孤子、调制不稳定性、模式形成和动态混沌。此外，它们有望为自旋波的操纵、放大和传输开辟新的可能性，以用于微电子器件中磁性纳米结构的应用。该项目汇集了两个世界领先的研究小组，在磁动力学和图案化磁性纳米结构方面拥有独特的经验。
