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.

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.
