Symmetry-broken dissipative exchange flows in thin-film ferromagnets with in-plane anisotropy
Ezio Iacocca, T. J. Silva, Mark A. Hoefer
Planar ferromagnetic channels have been shown to theoretically support a long-range ordered and coherently precessing state where the balance between local spin injection at one ed…
Breaking of Galilean invariance in the hydrodynamic formulation of ferromagnetic thin films
Ezio Iacocca, T. J. Silva, Mark A. Hoefer
Microwave magnetodynamics in ferromagnets are often studied in the small-amplitude or weakly nonlinear regime corresponding to modulations of a well-defined magnetic state. However…
Mode- and size-dependent Landau-Lifshitz damping in magnetic nanostructures: Evidence for non-local damping
Hans T. Nembach, Justin M. Shaw, Carl T. Boone +1
We demonstrate a strong dependence of the effective damping on the nanomagnet size and the particular spin-wave mode that can be explained by the theory of intralayer transverse-sp…
Propagation and control of nano-scale, magnetic droplet solitons
M. A. Hoefer, M. Sommacal, T. J. Silva
The propagation and controlled manipulation of strongly nonlinear, two-dimensional solitonic states in a thin, anisotropic ferromagnet are theoretically demonstrated. It has been r…
Theory for a dissipative droplet soliton excited by a spin torque nanocontact
M. A. Hoefer, T. J. Silva, Mark W. Keller
A novel type of solitary wave is predicted to form in spin torque oscillators when the free layer has a sufficiently large perpendicular anisotropy. In this structure, which is a d…
Time domain measurement of phase noise in a spin torque oscillator
Mark W. Keller, A. B. Kos, T. J. Silva +2
We measure oscillator phase from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of the phase nois…
