Manipulation of Coupling and Magnon Transport in Magnetic Metal-Insulator Hybrid Structures

Yabin Fan, Paige Quarterman, Joseph Finley, Jiahao Han, Pengxiang Zhang, Justin T. Hou, Mark D. Stiles, Alexander J. Grutter, and Luqiao Liu

Phys. Rev. Applied 13, 061002 (2020) - Published 15 June, 2020

Magnonic devices are important for implementing next-generation spintronics, but the adoption of such technology has long been stymied by the difficulty of integrating high-quality magnetic insulators with silicon. This study shows that highly effective magnonic spin valves can be realized at room temperature in Pt/YIG/permalloy hybrid structures grown on Si. In fact, a pronounced antiferromagnetic coupling between YIG and permalloy associated with growth on Si is the property that enables the spin valve’s functionality. Since these are two critical materials for spin-wave devices, this form of interfacial coupling between them is of great importance to spintronics.

Constructive Near-Field Interference Effect in a Birdcage MRI Coil with an Artificial Magnetic Shield

Phys. Rev. Applied 13, 064004 (2020) - Published 2 June, 2020

Commonly an artificial magnetic shield is used to improve antenna radiation in the far-field region, thanks to the in-phase reflection of electromagnetic waves. Here the authors study the possibility of constructive field interference with respect to the $n e a r - f i e l d$ region. This effect is useful in magnetic resonance imaging, where a conductive scanned sample (such as a patient) is located in the near-field region of radio-frequency coils. The team combines the most popular type of rf coil in magnetic resonance imaging, the “birdcage”, with an artificial magnetic shield, and demonstrate the near-field efficiency improvement, even at relatively low MRI frequencies.

Stable High-Speed Encryption Key Distribution via Synchronization of Chaotic Optoelectronic Oscillators

Fabian Böhm, Sevada Sahakian, Ann Dooms, Guy Verschaffelt, and Guy Van der Sande

Phys. Rev. Applied 13, 064014 (2020) - Published 5 June, 2020

Synchronization of chaotic photonic systems can be used, practically indefinitely, to create and distribute unique encryption keys ( $o n e - t i m e$ $p a d s$ ). However, typical photonic systems are highly susceptible to phase fluctuations and fundamentally limited in their key-generation rate. In this work, the authors demonstrate a fundamentally different approach based on chaotic optoelectronic oscillators (OEOs), with which highly stable synchronization can be achieved through commercial fiber-optic links. Contrary to current photonic systems, OEOs are $n o t$ limited by relaxation oscillations and allow significantly increased rates of key generation, for fast and stable data encryption.

Ultralow Mechanical Damping with Meissner-Levitated Ferromagnetic Microparticles

A. Vinante, P. Falferi, G. Gasbarri, A. Setter, C. Timberlake, and H. Ulbricht

Phys. Rev. Applied 13, 064027 (2020) - Published 11 June, 2020

Levitation of magnetic or superconducting microparticles is a promising technology for applications such as ultrasensitive force and gravity sensors, and experiments in fundamental and quantum physics. Unfortunately, achieving very low dissipation has proven to be more difficult than expected. This study demonstrates levitation of micromagnets by the Meissner effect above type-I superconductors, with very long damping times beyond 10 $^{4}$ s and quality factors exceeding 10 $^{7}$ . The authors furthermore investigate using a levitated micromagnet as an ultrasensitive magnetometer, pointing out the potential for magnetic-field resolution beyond the current state of the art.

Digitally Programmable Resonant Elastic Metamaterials

Christopher Sugino, Massimo Ruzzene, and Alper Erturk

Phys. Rev. Applied 13, 061001 (2020) - Published 5 June, 2020

Elastic metamaterials enable broadband control of vibration and wave propagation in structures, but their capabilities are limited by their fixed effective material properties. This work uses a piezoelectric metamaterial and digital control to create a $f u l l y$ $p r o g r a m m a b l e$ resonant band gap in a mechanical waveguide. Experiments demonstrate that the structure exhibits a resonant band gap that can be precisely tuned across a wide frequency range spanning several natural modes of the structure. This platform is expected to open doors to research on elastic metamaterials with effective properties that vary in space or time, significantly extending wave control in structures.
