Excitation of spin waves by spin polarized current
K. Rivkin, J. B. Ketterson
Numerical and analytical analysis is used to explain recently observed experimental phenomenon - excitation of spin waves in spin valves due to the applied spin polarized current.…
Switching spin valves using r.f. currents
K. Rivkin, J. B. Ketterson
We show that magnetization reversal in spin-injection devices can be significantly faster when using a chirped r.f. rather than d.c current pulse. Alternatively one can use a simpl…
Micromagnetic simulations of absoption spectra in magnetic nanodots, r.f. field perpendicular to the samples' plane
K. Rivkin, Lance DeLong, John B. Ketterson
Recently developed eigenvalue method is being used to calculate absorption spectra in magnetic square nanodots and nanodisks. Obtained results are being compared with both theoreti…
Micromagnetic simulations of absoption spectra
K. Rivkin, J. B. Ketterson
Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now a…
Magnetization reversal in the anisotropy-dominated regime using time-dependent magnetic fields
K. Rivkin, J. B. Ketterson
We study magnetization reversal using various r.f. magnetic pulses. We show numerically that switching is possible with simple sinusoidal pulses; however the optimum approach is to…
Controlling the Suhl instability: a numerical study
K. Rivkin, V. Chandrasekhar, J. B. Ketterson
Magnetization reversal (switching) using either r.f. fields or brute-force precessional switching is currently thought to ultimately be limited by the non-linear excitation of non-…
