YIG/CoFeB bilayer magnonic diode
Noura Zenbaa, Khrystyna O. Levchenko, Jaganandha Panda +9
We demonstrate a magnonic diode based on a bilayer structure of Yttrium Iron Garnet (YIG) and Cobalt Iron Boron (CoFeB). The bilayer exhibits pronounced non-reciprocal spin-wave pr…
All-magnonic repeater based on bistability
Qi Wang, Roman Verba, Kristyna Davidkova +8
Bistability, a universal phenomenon found in diverse fields such as biology, chemistry, and physics, describes a scenario in which a system has two stable equilibrium states and re…
Phase-resolved optical characterization of nanoscale spin waves
Ondřej Wojewoda, Martin Hrtoň, Meena Dhankhar +7
We study theoretically and experimentally the process of Brillouin light scattering on an array of silicon disks on a thin Permalloy layer. We show that phase-resolved Brillouin li…
Deeply nonlinear excitation of self-normalised exchange spin waves
Qi Wang, Roman Verba, Björn Heinz +9
Spin waves are ideal candidates for wave-based computing, but the construction of magnetic circuits is blocked by a lack of an efficient mechanism to excite long-running exchange s…
