Spin wave dispersion of ultra-low damping hematite () at GHz frequencies
Mohammad Hamdi, Ferdinand Posva, Dirk Grundler
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and…
Reversal of nanomagnets by propagating magnons in ferrimagnetic yttrium iron garnet enabling nonvolatile magnon memory
Korbinian Baumgaertl, Dirk Grundler
Despite the unprecedented downscaling of CMOS integrated circuits, memory-intensive machine learning and artificial intelligence applications are limited by data conversion between…
Terahertz Slonczewski propagating spin waves and large output voltage in antiferromagnetic spin-Hall nano-oscillators
Mohammad Hamdi, Dirk Grundler
We study theoretically antiferromagnet (AFM) based spin-Hall nano-oscillators (SHNOs) consisting of a nano-constriction (NC) in a thin-film uniaxial AFM. By solving the derived SW…
Spin Dynamics, Loop Formation and Cooperative Reversal in Artificial Quasicrystals with Tailored Exchange Coupling
Vinayak Shantaram Bhat, Sho Watanabe, Florian Kronast +2
Aperiodicity and un-conventional rotational symmetries allow quasicrystalline structures to exhibit unprecedented physical and functional properties. In magnetism, artificial ferro…
Magnetochiral Properties of Spin Waves Existing in Nanotubes with Axial and Circumferential Magnetization
Maria Carmen Giordano, Mohammad Hamdi, Andrea Mucchietto +1
We report experimental studies of spin-wave excitations in individual 22 nm thick Ni80Fe20 nanotubes with diameters of about 150 nm by means of Brillouin light-scattering (BLS) spe…
Multiband condensate of magnons in two dimensions
Joe Bailey, Pavlo Sukhachov, Korbinian Baumgaertl +7
Wavelike bosonic particles can accumulate in a single mode characterized by a particular wavelength, and such condensates are at the heart of phenomena such as superconductivity an…
