Dynamic magnetic response of infinite arrays of ferromagnetic particles
Kirill Rivkin, W. Saslow, L. E. De Long +1
Recently developed techniques to find the eigenmodes of a ferromagnetic particle of arbitrary shape, as well as the absorption in the presence of an inhomogeneous radio-frequency f…
Time-dependent fields and anisotropy dominated magnetic media
K. Rivkin, W. Saslow, J. Ketterson
We use a single dipole approximation to analyze the behavior of anisotropy-dominated magnetic nanoparticles subjected to an external r.f. field. We identify the steady state oscill…
Resonant switching using spin valves
K. Rivkin, J. Ketterson, W. Saslow
Using micromagnetics we demonstrate that the r.f. field produced by a spin valve can be used to reverse the magnetization in a magnetic nanoparticle. The r.f. field is generated us…
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
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-…
