Dynamic magnetization states of a spin valve in the presence of dc and ac currents: Synchronization, modification, and chaos
نویسندگان
چکیده
We present analytical and numerical calculations of dynamic magnetization states of a spin valve in the presence of dc and ac currents. Three distinct dynamic phases, synchronization, modification, and chaos, are identified within the experimental parameter space. A particularly interesting result is the appearance of the synchronization-chaos boundaries. In the region of synchronization, our results agree with experiments. In the modification and chaos regions, we predict experimentally observable power spectra.

Bifurcation and Chaos in Size-Dependent NEMS Considering Surface Energy Effect and Intermolecular Interactions
The impetus of this study is to investigate the chaotic behavior of a size-dependent nano-beam with double-sided electrostatic actuation, incorporating surface energy effect and intermolecular interactions. The geometrically nonlinear beam model is based on Euler-Bernoulli beam assumption. The influence of the small-scale and the surface energy effect are modeled by implementing the consistent ...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
