Spin-torque building blocks.
The discovery of the spin-torque effect has made magnetic nanodevices realistic candidates for active elements of memory devices and applications. Magnetoresistive effects allow the read-out of increasingly small magnetic bits, and the spin torque provides an efficient tool to manipulate - precisely, rapidly and at low energy cost - the magnetic state, which is in turn the central information m...
متن کاملEvaluation of Updating Methods in Building Blocks Dataset
With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...
متن کاملQuantum Spin Torque
M agnetoresistive random access memories (MRAMs)—a promising memory storage technology based on spintronics—store bits of information in spin valves consisting of junctions of two magnetic layers. To write data in a MRAM junction, a magnetic field switches the magnetization of one of the two layers. Recently, researchers started to explore a variation of the technique based on the spin-transfer...
متن کاملIntrinsic spin torque without spin-orbit coupling.
We derive an intrinsic contribution to the non-adiabatic spin torque for non-uniform magnetic textures. It differs from previously considered contributions in several ways and can be the dominant contribution in some models. It does not depend on the change in occupation of the electron states due to the current flow but rather is due to the perturbation of the electronic states when an electri...
متن کاملSpin Torque Driven Magnetodynamical Solitons
Magnetodynamical solitons are highly non-linear particle-like textures that derive their stability from an intrinsically dynamical state of their constituent spins. Although magnetodynamical solitons such as spin wave (SW) bullets can be sustained in ultra-low insulating magnetic films, such as YIG, using parametric pumping by external microwave fields [1], the advent of spin transfer torque va...
