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…
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-…
