Abstract

Control of spin wave transport in polymer 3D films was realized by magnetic microvolcanoes embedded in waveguides, fabricated by soft-matter specific techniques. Propagate of the spin wave signal excited in yttrium iron garnet (YIG) with 3D self-standing microvolcanoes chambers on top filled by the magnetic nanoparticles was evaluated by Brillouin light scattering and microwave spectroscopy. The magnetic moment of the polymer microvolcanoes varied with the change of the magnetic field bias direction inside the YIG films, which was shown by 2D mapping of the outer surface of the films. The good correlation of micromagnetic modeling and experimental data of spin wave propagation in the multistructure as a function of the applied magnetic field was clarified by the convergence parameters of the obtained polymer 3D magnetic microvolcanoes fields and the standard theory of spin wave propagation. The uniqueness of the soft materials object—polymer magnetic 3D films on conductive YIG film—lies in the application of the magnon network properties, which may find application in biomedical high-sensitivity feedback sensors.

带磁微火山的YIG波导中的自旋波传播：实验与模拟

采用软物质专用技术，在波导中嵌入磁性微火山，实现了聚合物三维薄膜中自旋波输运的控制。利用布里因光散射和微波光谱技术研究了自旋波信号在钇铁石榴石（YIG）中被激发的自旋波信号的传播。聚合物微火山的磁矩随薄膜内部磁场偏置方向的变化而变化，薄膜外表面的二维图显示了这一变化。所得聚合物三维磁微火山场的收敛参数与自旋波传播的标准理论阐明了自旋波在多结构中传播的微磁模拟与实验数据作为外加磁场函数的良好相关性。软性材料物体-聚合物磁性三维薄膜在导电YIG薄膜上的独特之处在于其磁振子网络特性的应用，它可能在生物医学高灵敏度反馈传感器中得到应用。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
