popup.description1
Establishing of the rules of magnetization dynamics in magnetic nanostructures under a parametric and/or combined (parametric and linear) pumping at fractional frequencies, and searching for the optimal conditions for frequency multiplication in these structures.
popup.description2
The possibility of resonant mode excitation in a spintronic nanostructure under the action of a fractional-frequency drive has been demonstrated, provided that the drive has combined parametric pumping and linear forces effects. A theory of parametric resonance in higher zones of parametric instability under the combined action of parametric and linear pumping has been developed, showing that combined resonance is possible only in even zones of instability and is thresholdless.
