Generation and routing of nanoscale droplet solitons without compensation of magnetic damping Open
Magnetic droplet soliton is a localized dynamic spin state which can serve as a nanoscale information carrier and nonlinear oscillator. The present opinion is that the formation of droplet solitons requires the compensation of magnetic dam…

Spin-orbit torque control of spin waves in a ferromagnetic waveguide Open
Spin-orbit torque (SOT) created by a spin current injected into a ferromagnet by an adjacent heavy metal represents an efficient tool for the excitation and manipulation of spin waves. Here we report the micromagnetic simulations describin…

Current-driven magnetization switching and dynamic spin reorientation transition in magnetic tunnel junctions Open
We present theoretical results on electrically induced magnetization dynamics in CoFeB/MgO/CoFeB tunnel junctions connected to a constant-current source. Our calculations take into account both the spin-transfer torque (STT) created by a s…

Spin injection and pumping generated by a direct current flowing through a magnetic tunnel junction Open
A charge flow through a magnetic tunnel junction (MTJ) leads to the\ngeneration of a spin-polarized current which exerts a spin-transfer torque\n(STT) on the magnetization. When the density of applied direct current exceeds\nsome critical …
