Abstract

The influence of a large spin-polarized current on the coupled dynamics of vortices in spin-transfer nanooscillators with a diameter of 400 nm is investigated. New stationary modes of coupled oscillations of vortices have been discovered, both for the same and opposite polarities of their cores. The dependence of the frequency of stationary coupled oscillations of magnetic vortices on the magnitude of the spin-polarized current has been studied. The found effect can be used to increase the operating frequencies of spin-transfer nano-oscillators.

期刊介绍： The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
