Spin-wave bandgap engineering via mode hybridization in dipolar-coupled YIG film/CoFeB nanodisk magnonic crystals
Junyoung Hyun, Krzysztof Szulc, Mateusz Zelent +5
We investigate spin-wave transport in hybrid two-dimensional magnonic crystals comprising a low-damping yttrium iron garnet (YIG) film coupled to a periodic array of CoFeB nanodisk…
Hybrid structure with a ferromagnetic film and an array of magnetic molecules for deep-nanoscale reprogrammable magnonics
Oleksandr Pastukh, Piotr Graczyk, Mateusz Zelent +2
Miniaturization is an essential element in the development of information processing technologies and is also one of the main determinants of the usability of the tested artificial…
Unveiling Micrometer-Range Spin-Wave Transport in Artificial Spin Ice
Syamlal Sankaran Kunnath, Mateusz Zelent, Pawel Gruszecki +1
Artificial spin ice (ASI) systems exhibit fascinating phenomena, such as frustration and the formation of magnetic monopole states, and Dirac strings. However, exploring the wave p…
Efficient Generation of Second-Harmonic Propagating Spin Waves in a Thin, Out-of-Plane-Magnetized Ferromagnetic Film
Mathieu Moalic, Youenn Patat, Mateusz Zelent +1
Spin waves are attractive information carriers owing to their gigahertz-to-terahertz frequencies, nanometric wavelengths, and negligible Joule heating. Yet the efficient excitation…
Stabilization of the skyrmion in a hybrid magnetic-superconducting nanostucture
Julia Kharlan, Mateusz Zelent, Konstantin Guslienko +2
Stabilization of skyrmions in a magnetic material without the Dzyaloshinskii-Moriya exchange interaction requires using of an inhomogeneous magnetic field, such as a demagnetizatio…
Beyond fixed-size skyrmions in nanodots: switchable multistability with ferromagnetic ring
Mateusz Zelent, Maciej Krawczyk, Konstantin Y. Guslienko
We demonstrate a novel approach to control and stabilize magnetic skyrmions in ultrathin multilayer nanostructures through spatially engineered magnetostatic fields generated by fe…
