A model for a spin-torque nano-oscillator based on the self-sustained oscillation of a
magnetic skyrmion is presented. The system involves a circular nanopillar geometry …

It has been proposed that high-frequency detectors based on the so-called spin-torque
diode effect in spin transfer oscillators could eventually replace conventional Schottky …

We fabricated vortex-type spin-torque oscillators (STOs) with optimized structures to
enhance the microwave emission power. Inserting a thin Co 70 Fe 30 layer between the …

The magnetisation dynamics of the vortex core and Landau pattern of magnetic thin-film
elements has been studied using holography with extended reference autocorrelation by …

We demonstrate how magnetic droplet soliton pairs, nucleated by two separated
nanocontact (NC) spin torque oscillators, can merge into a single droplet soliton. A detailed …

The transfer of spin angular momentum to a nanomagnet from a spin polarized current
provides an efficient means of controlling the magnetization direction in nanomagnets. A …

We show spin-transfer-torque-driven vortex oscillations in current-perpendicular-to-plane
giant magnetoresistance junctions using epitaxially grown Co 2 Fe x Mn 1− x Si (CFMS) …

We have carried out micromagnetic simulations of the gyrotropic resonance mode of a
magnetic vortex in the presence of spatially localized and spatially uniform out-of-plane …

We report magnetic vortex formation in epitaxially grown Co 2 Fe 0.4 Mn 0.6 Si (CFMS)
Heusler alloy discs that was confirmed using photoemission electron microscopy and the …

We investigate how the ability of the vortex oscillation mode of a spin-torque nano-oscillator
to lock to an external microwave signal is modified when it is coupled to another oscillator …
