Spin Torque in Semiconductor Single Planar Tunnel Junctions
نویسندگان
چکیده
Transport in a single planar tunnel junction with electrodes made of a ferromagnetic semiconductor is analyzed theoretically in the zero-temperature limit. Tunneling current and both (in-plane and out-of-plane) components of the spin torque exerted on one of the ferromagnetic electrodes are determined as a function of the angle θ between magnetic moments of the electrodes. The influence of the bias voltage and spin splitting of the electron band (in both electrodes) on the spin torque components is analyzed numerically.

متن کاملSpin torque, tunnel-current spin polarization, and magnetoresistance in MgO magnetic tunnel junctions.
We employ the spin-torque response of magnetic tunnel junctions with ultrathin MgO tunnel barrier layers to investigate the relationship between spin transfer and tunnel magnetoresistance (TMR) under finite bias, and find that the spin torque per unit current exerted on the free layer decreases by < 10% over a bias range where the TMR decreases by > 40%. This is inconsistent with free-electron-...

The bias dependence of the torque that a spin-polarized current exerts on ferromagnetic elements is important for understanding fundamental spin physics in magnetic devices and for applications. Several experimental techniques have been introduced in recent years in attempts to measure spin-transfer torque in magnetic tunnel junctions. However, these techniques have provided only indirect measu...

An important consequence of the discovery of giant magnetoresistance in metallic magnetic multilayers is a broad interest in spin dependent effects in electronic transport through magnetic nanostructures. An example of such systems are tunnel junctions – single-barrier planar junctions or more complex ones. In this review we present and discuss recent theoretical results on electron and spin tr...
متن کاملVoltage-induced ferromagnetic resonance in magnetic tunnel junctions.
We demonstrate excitation of ferromagnetic resonance in CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs) by the combined action of voltage-controlled magnetic anisotropy (VCMA) and spin transfer torque (ST). Our measurements reveal that GHz-frequency VCMA torque and ST in low-resistance MTJs have similar magnitudes, and thus that both torques are equally important for understanding high-frequen...
