Modulating Surface Acoustic Wave Generation through Superconductivity
Andrew Christy, Yuzan Xiong, Rui Sun +11
Surface acoustic waves (SAWs), with their five orders-of-magnitude slower propagation velocity, allow for considerably shorter wavelengths at the same frequency compared to electro…
Tuning Magneto-Optical Zero-Reflection via Dual-Channel Hybrid Magnonics
Andrew Christy, Yujie Zhu, Yi Li +7
Multi-channel coupling in hybrid systems makes an attractive testbed not only because of the distinct advantages entailed in each constituent mode, but also the opportunity to leve…
Edge-prompted spin waves probed via magneto-optical effect in the infrared
Junming Wu, Dinesh Wagle, Yuzan Xiong +7
Recent advances in magnonics highlight the need for employing spin wave characteristics as new state variables, which is to be detected and mapped out with high precision in all-on…
Phase-resolving spin-wave microscopy using infrared strobe light
Yuzan Xiong, Andrew Christy, Muntasir Mahdi +12
The needs for sensitively and reliably probing magnetization dynamics have been increasing in various contexts such as studying novel hybrid magnonic systems, in which the spin dyn…
Hybrid Magnonics with Localized Spoof Surface Plasmon Polaritons
Yuzan Xiong, Andrew Christy, Zixin Yan +8
Hybrid magnonic systems have emerged as a promising direction for information propagation with preserved coherence. Due to high tunability of magnons, their interactions with micro…
Combinatorial split-ring and spiral meta-resonator for efficient magnon-photon coupling
Yuzan Xiong, Andrew Christy, Yun Dong +6
Developing hybrid materials and structures for electromagnetic wave engineering has been a promising route towards novel functionalities and tunabilities in many modern application…
Magnon-Photon Coupling in an Opto-Electro-Magnonic Oscillator
Yuzan Xiong, Jayakrishnan M. P. Nair, Andrew Christy +5
The opto-electronic oscillators (OEOs) hosting self-sustained oscillations by a time delayed mechanism are of particular interest in long-haul signal transmission and processing. O…
Strong magnon-magnon coupling in an ultralow damping all-magnetic-insulator heterostructure
Jiacheng Liu, Yuzan Xiong, Jingming Liang +12
Magnetic insulators such as yttrium iron garnets (YIGs) are of paramount importance for spin-wave or magnonic devices as their ultralow damping enables ultralow power dissipation t…
