Antiferromagnetic droplet soliton driven by spin current
Roman V. Ovcharov, Mohammad Hamdi, Boris A. Ivanov +2
We demonstrate that a spin current flowing through a nano-contact into a uniaxial antiferromagnet with first- and second-order anisotropy can excite a self-localized dynamic magnet…
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…
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…
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…
Magnetoelastic coupling enabled tunability of magnon spin current generation in 2D antiferromagnets
Nasim Bazazzadeh, Mohammad Hamdi, Sungjoon Park +3
We theoretically investigate the magnetoelastic coupling (MEC) and its effect on magnon transport in two-dimensional antiferromagnets with a honeycomb lattice. MEC coeffcient along…
