Reset-set latch logic operation using vortex-gyration-coupled modes and its driven switching in magnetic-dot networks: A micromagnetic simulation study

open access: yesAIP Advances, 2019
We explored, by micromagnetic simulations, a new-concept RS (reset-set) latch logic operation based on magnetic-dot networks comprised of physically separated but dipolar-coupled three disks in magnetic-vortex states. To devise this robust RS latch logic

Unidirectional control of optically induced spin waves

open access: yes, 2017
Unidirectional control of optically induced spin waves in a rare-earth iron garnet crystal is demonstrated. We observed the interference of two spin-wave packets with different initial phases generated by circularly polarized light pulses.

SPIN-1 GRAVITATIONAL WAVES [PDF]

open access: yesInternational Journal of Modern Physics B, 2004
Gravitational fields invariant for a 2-dimensional Lie algebra of Killing fields [X,Y]=Y, with Y of light type, are analyzed. The conditions for them to represent gravitational waves are verified and the definition of energy and polarization is addressed; realistic generating sources are described.

Spin wave spectral probing of degenerate microstates in building-block of square artificial spin ice

open access: yesAIP Advances, 2021
We have investigated the spin wave modes of dipolar coupled, highly shape anisotropic magnetic nanoislands forming square artificial spin ice system by performing micromagnetic simulations using MuMax3 in combination with Matlab coding.

Separated spin-up and spin-down evolution of degenerated electrons in two dimensional systems: Dispersion of longitudinal collective excitations in plane and nanotube geometry

open access: yes, 2014
Applying the separated spin evolution quantum hydrodynamics to two-dimensional electron gas in plane samples and nanotubes located in external magnetic fields we find new kind of wave in electron gas, which is called the spin-electron acoustic wave ...

Optical Spin Waves

open access: yesNano Letters
Chirality is inherent to a broad range of systems, including in solid-state and wave physics. The precession (chiral motion) of electron spins in magnetic materials, forming spin waves, has various properties and many applications in magnetism and spintronics.

Realization of spin wave switch for data processing

open access: yesAIP Advances, 2018
In this work, experimental data on a spin wave switch based on spin wave interference is reported. The switch is a three terminal device where spin wave propagation between the source and the drain is modulated by the control spin wave signal.

Spin-Wave Propagation in the Presence of Interfacial Dzyaloshinskii-Moriya Interaction

open access: yes, 2013
In ferromagnetic thin films, broken inversion symmetry and spin-orbit coupling give rise to interfacial Dzyaloshinskii-Moriya interactions. Analytic expressions for spin-wave properties show that the interfacial Dzyaloshinskii-Moriya interaction leads to

Enhancement of the spin pumping efficiency by spin-wave mode selection [PDF]

open access: yes, 2010
The spin pumping efficiency of lateral standing spin wave modes in a rectangular YIG/Pt sample has been investigated by means of the inverse spin-Hall effect (ISHE).
