We investigate the electric-field effect on the exchange stiffness constant in a CoFeB/MgO
junction through the observation of the spin-wave resonance in a nanoscale magnetic …

An analytical study of the spectral line shape of ferromagnetic resonance (FMR) detected by
spin rectification effect and driven by the combined action of spin-transfer torque (STT) and …

We investigate the damping constant of a free layer with a perpendicular magnetic easy axis
in nanoscale CoFeB/MgO magnetic tunnel junctions (MTJs) with a reference layer with an in …

External magnetic field perturbation remains a key reliability issue for spin-transfer-torque
magnetic random-access memory. Although several prototypes have been demonstrated …

The characters of spin torque ferromagnetic resonance (ST FMR) are systematically studied
in the nanoscale ring-shape confined magnetic tunnel junctions (MTJs). Different from the …

Spin-torque oscillators (STOs) belong to a novel class of spintronic devices and exhibit a
broad operating frequency and high modulation rates. STOs take advantage of several …

The quantum Hall effect (QHE) is example of dissipationless electrical transport that can
occur when a large magnetic field is applied to a high mobility two-dimensional electron gas …

Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable
of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to …

This thesis describes magnetization dynamics in spin torque nano-oscillators and magnetic
tunnel junctions. In both cases a spin-polarized electrical current generates a spin torque …
