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…
Broken intrinsic symmetry induced magnon-magnon coupling in synthetic ferrimagnets
Mohammad Tomal Hossain, Hang Chen, Subhash Bhatt +5
Synthetic antiferromagnets offer rich magnon energy spectra in which optical and acoustic magnon branches can hybridize. Here, we demonstrate a broken intrinsic symmetry induced co…
Magnon-Magnon Interaction Induced by Dynamic Coupling in a Hybrid Magnonic Crystal
Rawnak Sultana, Mojtaba Taghipour Kaffash, Gianluca Gubbiotti +3
We report a combined experimental and numerical investigation of spin-wave dynamics in a hybrid magnonic crystal consisting of a CoFeB artificial spin ice (ASI) of stadium-shaped n…
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…
