چکیده
The combination of spin-orbit coupling driven effects and multiferroic tunneling properties is explored experimentally in thin Pt/Co/BaTiO3(BTO)/La2/3Sr1/3MnO3(LSMO) multilayers. presence a Pt heavy metal allows for the spin current-induced magnetization precession Co upon radio-frequency charge current injection. utilization BTO ferroelectric tunnel barrier separating LSMO ferromagnetic electrodes gives rise to both tunneling- magnetoresistance electroresistance. Using torque resonance, dynamics Co/Pt bilayers studied at room temperature. Unexpectedly, study same geometry performed low temperature reveals existence resonance peaks indicating efficient generation using Hall effect pumping that via barrier.

Ising spin model using Spin-Hall Effect (SHE) induced magnetization reversal in Magnetic-Tunnel-Junction
Ising spin model is considered as an efficient computing method to solve combinatorial optimization problems based on its natural tendency of convergence towards low energy state. The underlying basic functions facilitating the Ising model can be categorized into two parts, “Annealing and Majority vote”. In this paper, we propose an Ising cell based on Spin Hall Effect (SHE) induced magnetizati...
متن کاملMagnetization Dynamics Symmetry in Spin Torque Induced Magnetization Switching
Magnetization dynamics symmetry plays important roles in magnetization switching. Here we study magnetic field and spin torque induced magnetization switching. Spin moment transferring from polarized itinerant electrons to local magnetization provides a magnetization switching mechanism without using external magnetic field. Besides its importance in fundamental magnetization switching dynamics...
متن کاملSpin dynamics in a tunnel junction between ferromagnets
The dynamics of a single spin embedded in the tunnel junction (quantum point contact) between ferromagnets is addressed. Using the Keldysh technique, we derive a quantum Langevin equation. As a consequence of the spin-polarization in the leads, the spin displays a rich and unusual dynamics. Parallel configured and equally strong magnetic moments in the leads yield an ordinary spin precession wi...

We theoretically study the recently observed tunnel-barrier-enhanced dc voltage signals generated by magnetization precession in magnetic tunnel junctions. While the spin pumping is suppressed by the high tunneling impedance, two complementary processes are predicted to result in a sizable voltage generation in ferromagnet F insulator I normal metal N and F I F junctions with one ferromagnet be...
متن کاملSpin current through a tunnel junction
We derive an expression for the spin-current through a tunnel barrier in terms of many-body Green’s functions. The spin current has two contributions. One can be associated with angular-momentum transfer by spin-polarized charge currents crossing the junction. If there are magnetic moments on both sides of the tunnel junction, due to spin accumulation or ferromagnetic ordering, then there is a ...
