在这篇综述中，我们考虑的二维自旋波（SW）孤子，所谓的SW子弹和SW液滴的属性相关的理论和实验结果。这种非线性自定域SW模具有非常有趣的物理性质，在现代和未来的磁电子学和自旋电子学中具有实际应用。本文的实验和理论研究结果证明了SW子弹在磁性薄膜和受限磁性纳米结构中的存在（磁性纳米接触），阐明了一维非线性SW孤子、二维非线性SW子弹和线性自旋波包性质之间的本质区别，以及自生成、参数激发、和相位共轭的SW子弹，类似于传统的线性自旋波的情况下。此外，在这篇评论中，我们提出了实验结果证明成核，动力学和湮灭的二维强非线性SW“液滴”的自旋扭矩驱动的磁性纳米接触。利用最近发展的理论模型分析了这些奇异非线性物体的特性，并通过微磁数值模拟进行了说明。在这篇综述中，我们考虑了与二维自旋波（SW）孤立子（所谓的SW子弹）特性相关的理论和实验结果。SW液滴。这种非线性自定域SW模具有非常有趣的物理性质，在现代和未来的磁电子学和自旋电子学中具有实际应用。本文的实验和理论研究结果证明了SW子弹在磁性薄膜和受限磁性纳米结构中的存在（磁性纳米接触），阐明了一维非线性SW孤子、二维非线性SW子弹和线性自旋波包性质之间的本质区别，以及自生成、参数激发、和相位共轭的SW子弹，类似于传统的线性自旋波的情况下。此外，在这篇综述中，我们提出了实验结果表明成核，动力学，和湮灭的二维…
In this review, we consider theoretical and experimental results related to the properties of two-dimensional spin-wave (SW) solitons, so-called SW bullets and SW droplets. Such nonlinear self-localized SW modes possess very interesting physical properties, and could have practical applications in modern and future magnonics and spintronics. The experimental and theoretical results presented in this review have undeniably proven the existence of SW bullets in magnetic films and confined magnetic nanostructures (magnetic nanocontacts), and have elucidated the essential distinctions between the properties of the one-dimensional nonlinear SW solitons, two-dimensional nonlinear SW bullets and linear spin wave packets, as well as the possibility of self-generation, parametrical excitation, and phase-conjugation of the SW bullets, similar to the case of the conventional linear spin waves. Also, in this review we presented experimental results demonstrating the nucleation, dynamics, and annihilation of two-dimensional strongly nonlinear SW “droplets” in spin-torque-driven magnetic nanocontacts. The properties of these exotic nonlinear objects are analyzed using recently developed theoretical models and illustrated by micromagnetic numerical simulations.In this review, we consider theoretical and experimental results related to the properties of two-dimensional spin-wave (SW) solitons, so-called SW bullets and SW droplets.
