Bright and dark states of two distant macrospins strongly coupled by phonons
Kyongmo An, Ryuhei Kohno, Artem N. Litvinenko +10
We study the collective dynamics of two distant magnets coherently coupled by acoustic phonons that are transmitted through an intercalated crystal. By tuning the ferromagnetic res…
Excitation of whispering gallery magnons in a magnetic vortex
K. Schultheiss, R. Verba, F. Wehrmann +10
One of the most fascinating topics in current quantum physics are hybridised systems, in which different quantum resonators are strongly coupled. Prominent examples are circular re…
Identification and selection rules of the spin-wave eigen-modes in a normally magnetized nano-pillar
Vladimir V. Naletov, Grégoire De Loubens, Gonçalo Albuquerque +12
We report on a spectroscopic study of the spin-wave eigen-modes inside an individual normally magnetized two layers circular nano-pillar (PermalloyCopperPermalloy) by means o…
Dynamic origin of azimuthal modes splitting in vortex-state magnetic dots
Konstantin Y. Guslienko, Andrei N. Slavin, Vasyl Tiberkevich +1
A spin wave theory explaining experimentally observed frequency splitting of dynamical excitations with azimuthal symmetry of a magnetic dot in a vortex ground state is developed.…
Temperature dependence of nonlinear auto-oscillator linewidths: Application to spin-torque nano-oscillators
V. S. Tiberkevich, A. N. Slavin, Joo-Von Kim
The temperature dependence of the generation linewidth for an auto-oscillator with a nonlinear frequency shift is calculated. It is shown that the frequency nonlinearity creates a…
Excitation of self-localized spin-wave "bullets" by spin-polarized current in in-plane magnetized magnetic nano-contacts: a micromagnetic study
G. Consolo, B. Azzerboni, G. Gerhart +3
It was shown by micromagnetic simulation that a current-driven in-plane magnetized magnetic nano-contact, besides a quasi-linear propagating ("Slonczewski") spin wave mode, can als…
