Nano-patterned magnonic crystals based on ultrathin YIG films
M. Collet, M. Evelt, V. E. Demidov +9
We demonstrate a microscopic magnonic-crystal waveguide produced by nano-patterning of a 20 nm thick film of Yttrium Iron Garnet. By using the phase-resolved micro-focus Brillouin…

Direct observation of dynamic modes excited in a magnetic insulator by pure spin current
V. E. Demidov, M. Evelt, V. Bessonov +11
Excitation of magnetization dynamics by pure spin currents has been recently recognized as an enabling mechanism for spintronics and magnonics, which allows implementation of spin-…

Spin wave amplification using the spin Hall effect in permalloy/platinum bilayers
O. Gladii, M. Collet, K. Garcia-Hernandez +8
We investigate the effect of an electrical current on the attenuation length of a 900 nm wavelength spin-wave in a permalloy/Pt bilayer using propagating spin-wave spectroscopy. Th…
