Current-driven excitations in symmetric magnetic nanopillars.
We study experimentally the current-driven magnetic excitations in symmetric Co/Cu/Co nanopillars. In contrast with all the previous observations where the current of only one polarity is capable of exciting a multilayer system saturated by an externally applied magnetic field, we observe that both polarities of the applied current trigger excitations in a symmetric multilayer. This may indicat...
متن کاملSpin-transfer excitations of permalloy nanopillars for large applied currents
Using measurements of the spectra of microwave-frequency resistance oscillations, we determine the roomtemperature phase diagram of magnetic excitations caused by torques from dc spin-polarized currents in thin permalloy /copper/ thick permalloy multilayer samples. We extend the measurements to larger values of current than have been reported previously. We find several additional modes that we...
متن کاملSpin-transfer torque in magnetic multilayer nanopillars
We consider a quasi one-dimensional configuration consisting of two small pieces of ferromagnetic material separated by a metallic one and contacted by two metallic leads. A spinpolarized current is injected from one lead. Our goal is to investigate the correlation induced between the magnetizations of the two ferromagnets by spin-transfer torque. This torque results from the interaction betwee...
متن کاملCurrent-induced excitations in single cobalt ferromagnetic layer nanopillars.
Current-induced excitations in Cu/Co/Cu single ferromagnetic layer nanopillars ( approximately 50 nm in diameter) have been studied experimentally as a function of Co layer thickness at low temperatures for large applied fields perpendicular to the layers. For asymmetric junctions current-induced excitations are observed at high current densities for only one polarity of the current and are abs...
متن کاملQuantitative study of magnetization reversal by spin-polarized current in magnetic multilayer nanopillars.
We have studied magnetic switching by spin-polarized currents and also the magnetoresistance in sub-100-nm-diam thin-film Co/Cu/Co nanostructures, with the current flowing perpendicular to the plane of the films. By independently varying the thickness of all three layers and measuring the change of the switching currents, we test the theoretical models for spin-transfer switching. In addition, ...
