Shaping non-reciprocal caustic spin-wave beams
Dinesh Wagle, Daniel Stoeffler, Loic Temdie +8
A caustic is a mathematical concept describing the beam formation when the beam envelope is reflected or refracted by a manifold. While caustics are common in a wide range of physi…
Deeply nonlinear magnon-photon hybrid excitation
Dinesh Wagle, Anish Rai, M. Benjamin Jungfleisch
We investigate the microwave-power dependence of magnon-photon coupling in a yttrium iron garnet-sphere/split-ring-resonator hybrid system at room temperature and demonstrate that…
Spin pumping driven by magnon-polaritons in a ferromagnet-coplanar superconducting resonator hybrid system
Dinesh Wagle, Yi Li, Anish Rai +3
We demonstrate spin pumping driven by a strongly coupled magnon-photon system using a ferromagnet-coplanar superconducting resonator hybrid system at 1.4 K. Electrical readout via…
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…
Observation of thermally activated coherent magnon-magnon coupling in a magnonic hybrid system
Dinesh Wagle, Yi Li, Mojtaba Taghipour Kaffash +4
We experimentally demonstrate strong magnon-magnon coupling by thermal spin excitations in yttrium iron garnet/permalloy (YIG/Py) hybrid structures using microfocused Brillouin lig…
