Theoretically, in the case of the asymmetric structure of trilayers with opposite sign of spin Hall angle, both damping like torque and field like torque due to the SHE and the Rashba effect will be enhanced. Using the harmonic measurements, we have characterized the effective fields corresponding...
We start by measuring the DW velocity vs. the out-of-plane magnetic field (HZ) without applying Hip(Fig.3a). We prepare bubble domains in an un-patterned film by applying a small HZfield. To reach the flow DW motion and avoid the influence of pinning, we apply strong (up to −217...
1a), exerting antidamping spin torque on its magnetization M14. To maximize the antidamping effect of spin current, the magnetization in the studied devices was saturated by the in-plane static magnetic field H0 = 1–2 kOe applied perpendicular to the direction of the current flow. At...
Proportionally, the torque generated on the lever arm in reference to the lever arm axis of rotation R-R by the force F4 is larger when the lever arm moves in the −A direction than when the lever arm moves in the direction +A. The value of the torque on the lever arm when the ...
E, electric field strength in the electrorheological fluid; H, magnetic field strength in the magnetorheological fluid; KD, feedback gain in active damping. Consider a single-degree-of-freedom (SDOF) system, as shown in Figure 2. The equation of motion for the system is given by: Sign in...
A torque damping device including a support disc, a second guide washer provided with pressed sections and an intermediate hub disc. The support disc has elastic clamps acting on the hub disc for push
Spin-orbit torque magnetization switching in a perpendicularly magnetized ferromagnetic-semiconductor single layer:Damping like torque and field like torqueSpin-orbit torque (SOT) magnetization switching, which is induced by a spin current generated by a charge current, is a promising phenomenon that can...
We find analytic expressions for the damping- and field-like spin-transfer torques generated at the interface between two fully spin-polarized ferromagnetic metals (half-metals). The proposed one-dimensional model shows that in the case of nonidentical ferromagnets the field-like torque can exhibit ...
Closed-loop systems including "end-point damping" capabilities have been designed specifically for motors other than d-c servo motors, such as multi-phase stepper motors and the like. When the presence of such closed-loop systems enables the use of cheaper and less powerful stepper motors, the...
Apparatus for damping vibrations between an engine and a power train has two coaxial flywheels and at least one damper which operates between and opposes rotation of the flywheels relative to each oth
