Magnetic field direction influence on the spectrum of spin waves output signals at three-magnon decay of magnetostatic surface waves in a cross based on waveguides of yttrium iron garnet film [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика, 2020
Subject. We studied the effect of magnetic field H direction on the spectrum of the output signals in a 4-port cross-shaped structure where magnetostatic surface waves (MSSW) are excited by an input transducer under the condition of the first-order ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Terminations for magnetostatic waves

Electronics Letters, 1980
Magnetostatic wave (m.s.w.) devices can exhibit multiple reflections due to finite sample dimensions. By reducing the magnetic bias field in the end regions of the sample using soft iron rods, these reflections can be eliminated. This has been demonstrated by pulse delay measurements.

Bias‐Engineered Synthetic Antiferromagnets Hosting Sub‐20 nm Zero‐Field Skyrmions at Room Temperature

Advanced Science, EarlyView.
A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.

Enhanced High Dimensionality and the Information Processing Capacity in Interfered Spin Wave‐Based Reservoir Computing, Achieved With Eight Detectors

Advanced Electronic Materials, EarlyView.
Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Dipolar spin waves in uniaxial easy-axis antiferromagnets: A natural topological nodal-line semimetal

Physical Review Research, 2020
The existence of magnetostatic surface spin waves in ferromagnets, known as the Damon-Eshbach mode, was recently demonstrated to originate from the topology of the dipole-dipole interaction.

Bias-free spin-wave propagation in a micrometer-thick ferrimagnetic film with perpendicular magnetic anisotropy

AIP Advances, 2022
The isotropic transmission of magnetostatic forward volume spin waves in magnetic films with perpendicular magnetic anisotropy (PMA) is shown to be useful in the implementation of magnon-based micro-conduits.
